What to upgrade to....

Hi.
By the end of next week, my system will have the following specs (just a change of processor really):

AMD Athlon 64 X2 3800
Abit AN8 Ultra.
2Gb GeIL Value PC3200 CAS 2.5 (4x512Mb).
Connect 3D Radeon X800XL 256Mb PCI-E.
80Gb Hitachi SATA2.
2x250Gb Hitachi SATA2.
Lite-On 16x DVD.
Lite-On 8x DVDRW.
2x Samsung 172X 17” TFTs.
Antec TrueBlue 480W Rev1 (20pin).
Logitech MX1000 Wireless Laser Mouse.
Apple ProUSB Keyboard
Onboard AudioMax 7.1, outputs to Cambridge Audio AV Receiver & some 5.1 Medusa headphones.

Im fairly confident in saying that short of running at rediculus resolutions that with a good graphics card i'd handle almost anything i could throw at it.

The thing is, what graphics card would be recommended to replace my X800XL?
I take that the GX2s need a SLI mobo to run?

Thanks in advance all.

Reasonably flexable really.
Depends on what im getting for my money really.
Im thinking around £250.

I havnt really been keeping up with tech news lately apart from the big announcements, so i dont know what sort of video card would be best paired with my processor.

I was looking at those two cards tbh.
Im tempted by the ATI because im lazy and dont want to reinstall everything. lol.

 

[BoomAM]

I know that. I just wont have to reinstall the OS sticking with ATI! lol.

So nVidia have cleaned up their act a bit now have they in regards to driver uninstallations?
Hmm.
The 7900GT looked interesting to me, as its the same 'physical' specs as a GTX, just clocked slower.

Another consideration is noise. The stock ATI coolers are quite loud arnt they?

The X1800XT seems tempting. I think i'd prefer to get an Artic Cooler on it over a Zalman though tbh.

Quick question thats slightly off topic:
I currently have a 480W Antec PSU. 20pin. Runnng the system you can see above. Am i likely to see power issues when moving to an X2 and/or when i wack in a X1800XT or above video card?
