THANKS a lot guys its much appreciated.

One more question.

whats worth it more. a 6850 or 1 4870 x2.

i have a 4870 right now in my rig was thinking of crossfire?

how much % more does a third card if like in games?

will i at least have solid 60 fps in all games with trifire 4870? at 1080p max settings?

Depends on scaling, if the game even supports Crossfire and if you want immense power draw for the performance. Two 6850's would be worlds better.

6850 for lesser TDP idle/load and DX11 features, although the 4870X2 is one beastly card. Having TRIFIRE 4870 setup would max out 99.9% of games@1080P with available DX10(.1) features.

go for the 68xx series, less power and heat.
post #15 of 19
At this point I would not get a 4870x2. They produce a lot of heat and are power hungry. Plus you need to make sure that game supports multiple cards. However the 4870 x2 would outperform the 6850.

I would suggest looking into a second hand 5870.

All im going to play is Starcraft 2 and The Witcher 2.

The cost for me getting a 4870 x2 is maybe 120. n i get trifire

The cost of me getting 2 6850 is like 350?

Then spend the $120 and get the X2.

Or sell the 4870 and pick up a second X2 and dominate all.
post #18 of 19
I prefer 1 stronger GPU to multiple weak(er) GPUs just because what if the game doesn't support crossfire, or the CF drivers suck?

Plus with the 5k/6k series you get DX11 which is nice...not sure how 10.1 Bad Company 2 looks but DX11 is beautiful! (and easily maxed!)
