Crossfire or not to Crossfire (6850 vs 7850)

post #1 of 4
Thread Starter 
Weird Title I know.

I am changing my 775 rig to a X48 or P45 and I want other opinions. Should I get another 6850 and crossfire or should I get a 7850?

Also yes I thought of getting a 7950 but I dont need it. 7870 Is in my brothers Rig so I'd most likely for go my own to crossfire his. Also the 6850 Is an HIS IceQ X Turbo.

Get a 7850, when overclocked properly, it performs just as fast as SLI 6850's, if you can add 10$ more, get the 660 Non ti, and you can get Advanced phys X, plus it's faster than the 7850. Then if you can add a little more, say, 40$ get the 7870xt, equal to, or faster than a 660 TI when overclocked properly. Either way, go single card for now, the cards i listed are faster than 6850 X fire thumb.gif

GTX 660s or Tis aren't very good price/performance, you'd be better off getting a 7870 or a 7870 LE - which can both be had in that price-range.
That said I'd go with either of the above, 2GB 7850s aren't much cheaper than 7870s really, you can get them for just over $200 AR or another $30 for the LEs.

sell your HD 6850 and go for a single GPU. go for a HD 7950 boost. if you cannot afford it atleast get a HD 7870 Tahiti LE.

http://www.techpowerup.com/reviews/Club_3D/HD_7870_jokerCard_Tahiti_LE/28.html

HD 6850 - 53
HD 7870 Tahiti LE - 100
HD 7970 - 122

easily close to twice (2x) HD 6850 perf. overclocks to 1.2 ghz and matches HD 7970(925 Mhz) performance.
