which is better for games?XFX GeForce 7300 LE 512mbDDR2 or XFX GeForce 6800 256mbDDR3 in PCI-E?

Answer 1

Well the people who just looked at the higher number an answered are wrong. Now you didn't specify whether it was 6800GT or GS, not that it matters they will both blow the 7300LE away. Remeber that while the 7300 is from the next generation of cards, it is the low-budget version of that generation, while the 6800 is the high end model of its generation. The 6800 has faster memory, has a better memory interface, and 4 times as many pixel pipelines, it is a far superior card.

Answer 2

I'll definitely vote for GeForce 7300 LE because there are many features and improvements that 7300 LE have, but 6800 didnt.

Answer 3

Something general to look for... the number of mb DDR is the video RAM (Random Access Memory) of the video card. Performance wise for games generally the more video ram the better. It allows for faster display, smoother motion and higher detail level.

Answer 4

GeForce 7300

ATI Crossfire!
...............
ATI Technologies Inc., founded in 1985, acquired by AMD in 2006, was a major designer of graphics processing units and video display cards.

As a fabless semiconductor company, ATI conducts research & development of chips in-house, but subcontracts the actual (silicon) manufacturing and graphics-card assembly to third-parties. The production-chain of a chip involves multiple third-parties: the foundry (UMC and TSMC) makes processor wafers, the test-house tests the dies for defects and sorts them based on performance-characterization and the packager seals individual dies in a hardened case. In terms of inventory management, ATI must place foundry orders months in advance of their planned sale, then hold the produced chips in a warehouse until final delivery. The long lead time between order and delivery, combined with market uncertainty, leads to occasional supply/demand imbalances.

On July 24, 2006, AMD and ATI announced a plan to merge together in a deal valued at US$5.4 billion. The merger closed October 25, 2006 (Press Release). The acquisition is being paid for with $4.2 billion, which includes over $2 billion financed from a loan, as well as 56 million shares of AMD stock. [1]

CrossFire
is a brand name for ATI Technologies multi-GPU solution, which competes with its rival nVidia's Scalable Link Interface (SLI). The technology allows a pair of graphics cards to be used in a single computer to improve graphics performance. Although only recently announced for consumer level hardware, similar technology known as AMR has been used for some time in professional grade cards for flight simulators and similar applications available from Evans & Sutherland.

Advantages over NVIDIA SLI
ATi has opened the Crossfire architecture to Intel, allowing CrossFire to be enabled on certain Intel chipsets which boast two 16x PCI-E slots. SLI, however, requires an nForce motherboard which is SLI certified (such as the nForce 590 SLI).
Lower to midrange CrossFire implementations do not require the cumbersome Y-dongle that is required for the old high-end CrossFire configurations, this in turn does away with any type of external connector and uses the PCI-e bus as the main means for CrossFire interconnects and communication.
The new ATI CrossFire bridge has a higher bit width than SLI, while clocked a little slower. The connection is split into two 12 bit parallel channels, while both connectors are not technically needed for hardware CrossFire operation, software does not currently permit CrossFire to be run on a single CrossFire bridge. This new bridge also allows for easier introduction of multi-GPU configurations beyond pairs.[3]

Rendering modes

The CrossFire system supports four different rendering modes, each offering their own specific advantages and disadvantages.
SuperTiling: CrossFire's standard dual-GPU rendering mode. It divides the screen up like a checkerboard, allocating adjacent squares ('quads') to alternate GPUs. (To continue the checkerboard analogy, one card would render the white squares, and the other the black). SuperTiling supports all Direct3D applications (but not OpenGL). However, it provides the least performance enhancement of the four modes, a rough estimate being 1.15 times the power of a single equivalent GPU. This is due to the fact that SuperTiling does not allow the geometry of a scene to be scaled between two cards. It is worth noting that SuperTiling only works on cards that have an even number of pixel quads so a setup with an X800 with 12 pixel pipelines paired with an X800 master card will not be able to render the SuperTiling mode.
Scissor: Divides the screen into two rectangles, one above the other. This is the default operating mode for OpenGL-based applications. Unfortunately, the performance boost with Scissor mode is approximately equal to the SuperTiling mode. This render mode is more commonly known as Split Frame Rendering (SFR), which is how nVidia refers to it in SLI. In theory, SuperTiling should provide higher performance, because there is a better chance the work will be evenly divided between the two cards. Using Scissor mode means that the system has to carefully choose the "cutting point" in order to balance the load.
Alternate Frame Rendering: The fastest mode, Alternate Frame Rendering (as the name suggests) sets one GPU to render odd frames, and one the even frames. While this produces a high performance boost, it is incompatible with games using render-to-texture functions because one card doesn't have direct access to the texture buffer of the other. Like nVidia, ATI uses game profiles for Alternate Frame Rendering, and while nVidia allow you to create profiles to use AFR on any application, ATi will only allow such a change for DirectX games.
CrossFire Super AA: This mode is not designed for a large increase in frames per second; rather, it is intended to improve the quality of the frames rendered (hence 'Super AA' - super anti-aliasing). Super AA is able to double the anti-aliasing factor (eg. 4x, 8x and 12x) without any drop in framerate.
