dell xps video cards comparison?

[Sony]

Hi,
I was looking to buy a new pc and was considering Dell XPS models, I see for video cards (256mb) they have:
256MB PCI Express™ x16 (DVI/VGA/TV-out) ATI Radeon X600 SE HyperMemory
256MB PCI Express™ x16 (DVI/VGA/TV-out) nVidia GeForce 6800

Now the model I was considering was XPS 400, is there big difference between those two cards?. The 1st one to add onto the desktop was only $40 more, while the 2nd one was $110 more.

I was planning to mainly use this as a gaming pc, thus the XPS and the video card question :D

Thank you.

Try avoiding ATI's HyperMemory or nVidia's TurboCache. The cards swallow system memory to compensate for the lack of vRAM. If those are your only two choices, go with the GF6800 for gaming. The Radeon X600SE, on top of having HM, will give you nowhere near the performance you will get with the 6800.

6800 - Much better card, much better gaming performace, and doesn't use system RAM like Kram said.

Thanks for the responses, I'll get the 6800 then, just wanted to make sure the price difference was justified. Thanks for the advise!:cool:
