i'm buying a amd x2 4200, a8ne SLI premium, 1 gb ddr400 ram(in a mth or 2 will be upgraded to 2gb), 250gb western digital hdd. i wanted to know if it is better to go for 6800XT 512mb sli or 7900GT 256mb sli. i'm planning to use this comp for maya(3d application) and gaming of course. i was going to buy a quadro fx card, but then its only the high end cards that support pixel shader 3 and i can't afford that. which one should i go for?

The 6800XT and 7900GT should not be mentioned in the same sentence. The 6800XT is a $hit card; a crippled 6800 with 8 pipelines and, in some cases, 128-bit memory. A single 7900GT will beat the $hit out of 6800XTs in SLI.

Every card is going to have a GPU paired with an adquate ammount of memory at the very least these days, the only time memory becomes important is when you are comparing two GPUs that are on the same level with one another. A large ammount of RAM on a lower class GPU won't make it faster. What I am saying is GPU is more important then memory these days.

A dictionary. (sorry, couldn't resist.)

Its not just about pipelines, but memory bus, memory type, core/mem clock speeds (when looking at identical chips, like the NV43, etc), core, and a host of other things.

A single 7900GT will out-do SLI 6800XTs by a mile. 6800XT (also known as LE sometimes) has only 8 pipes (which you may be able to unlock to 12 or 16 if lucky) and possibly a 128-bit bus. 7900GT comes with 24 pipes out of the box (not 20 like someone else incorrect quoted) and a 256-bit memory bus with a good chance of reaching 7900GTX speeds. With a single card you get better compatibility, lower power consumption, better upgrade flexibility, less heat output, the list goes on. Besides I am yet to see where SLI is a sensible investment anywhere, it seems that upgrading a single card to a next-gen single card is better than dual last-gen cards (and less expensive).

Anything-512mb on a card other than the absolute top-end is a marketing ploy for people who don't know what the memory does for a video card.

6800GT was a good card, even SLI with that would probably get slotted by a 7900GT. So seriously, why anyone would ever buy SLI is beyond me. Just get the single 7900GT, stop listening to anything that retarded dealer might say to you and forget all about SLI.

Unless you really need the OpenGL/CAD support you don't want QuadroFXs. The FX 4400 (for a start) is based on GeForce 6-technology, it is the chip using in the 6800 PCIe series. It's old, it's slow, you don't want it.

The FX 5500 uses an identical chip to the 7900GT/GTX (the G71 core). It has (to all intents and purposes) exactly the same power as a 7900GT. You are literally paying for a few tweaks on a PCB (i.e. in the past it was shown that a few rewirings could turn a GeForce into a Quadro).

Because it's designed for professionals as opposed to consumers, the thinking being that they can afford it, even though the silicon is exactly the same. Though given the argument of cost, it probably costs them about 5% of the final selling price for the actual manufacture of a piece of silicon. Other costs are R&D, advertising, PCB design, chip design, etc. and they make those up by pricing their products appropriately.
