A few months back I got a Dell Optiplex GX620 from work to take home, it has a Radeon X600 Pro in it which is okay for WoW but if I want to play CS:S at 1280x1024 it struggles a bit! I have about £150 to spend on a card and have narrowed it down to two (well three, one is a bit expensive) - Also the Dell is a BTX machine, which I dont *think* has one of those PCI-X power connectors on the PSU. Can I get a molex -> PCI-X connector? And will a normal card fit in a PCI-X motherboard?
Anyway, onto my selection;
ATI:
PowerColor ATI Radeon X800 GTO16 256MB GDDR3 TV-Out/DVI (PCI-Express) - Retail (GX-055-PC) - £129.19
nVidia:
Gigabyte GeForce 6800 GS 256MB GDDR3 TV-Out/Dual DVI (PCI-Express) & Quake 4 Bundle - Retail (GX-016-GI) - £146.82
Push the boat out, if its *really* worth the cash:
XFX GeForce 6800 GS Extreme XXX Edition 256MB GDDR3 TV-Out/DVI (PCI-Express) - Retail (GX-056-XF) - £158.57
Which one do you lot think?
Cheers
