What GPU is better

[OpticalxLX3]

A single HD 4890 or 2 HD 5670?

HD 4890 of course, but the card leads by not too much like say 8%

It is not that obvious - HD 4890 has 800SP and HD 5670 has 400SP (*2=800SP too) One caed is always better than two because of drivers for some games...

Well yeah your right, one good card is better than two middle end cards, but for example your playing Avatar and it gives 22 fps on 1920x1200 maxed out, and when you play the same game maxed out same settings with dual Video cards Cross fire it doubles fps, from single you get 22 fps and from dual you get 2x the fps 44 fps ?

No, SLI/CF cant scale at 100% (mostly) - it depends on games Some games can have almost doubled framerate but other games can have only 40% more...because of this it is always better to have one card. On the other hand HD 4890 hasnt DX11 so if Opti want to play DX11 game, HD 5670 will be better

Hmm my old PC has an nVidia GeForce 6200 GE and it doesn't have even DX 10 support and yet i have DX 11 and Crysis Warhead runs ok with a little lag on lowest but it's still playable... ????

[devilek]

Because warhead is not a DX10 native game

I know a HD 4890 is kind of better but 2 HD 5670 are quieter,don't require much wattage and are newer.

Best advice for every single user is, that the needs are most important - do it like you wanted to be

I totally agree with that but i can get a HD 4890 for 60-70 euros and 2 HD 5670 for 100 euros so thats why I'm asking but I'll probably buy a HD 4890 and upgrade in a year or something like that.
