As far as singlecards, GTX285 2GB and HD4890 are the top cards, with nvidia and ati respectively. For nvidia, the asus MARS(limited edition though) is the best for dual gpu singlecard, while as far as standard availablity the GTX295 is the best. For ATi, the 4870x2 is the best single card dual gpu card.The GTX 295 is the best, but the GTX 295 is actually just two gtx 275's. If you want the best, perse, Then get two GTX 280's and SLI them
for Ati, i do believe the 4870 X2 is still the top.
True, for workstation uses though. The main difference is the added vram and the bios/drivers though, they use the same core as the current desktop video cards. Plus they suck for gaminghmm... you guys seem to of forgotten some of those crazy workstation cards. The nVidia Quadro FX5800 or ATI FireGL V8650, for example. Those are probably the best graphics cards available at the moment.
