Here's my PC:
Intel Core 2 Duo E8400 Processor OC'd to 4.0 GHz
8GB DDR2 RAM OC'd @ 1186 MHz
550W Rosewill Power Supply
HIS HD 6850 GPU 1GB
Asus Xonar DX Sound Card
Asus P5Q Pro Motherboard
Planar 27" LCD Monitor (1920x1080 resolution)
Here is the Math for my upgrade options. The -$50 is a Newegg gift card.
What do YOU think would provide the most bang for the buck?
GRAPHICS CARD SOLUTIONS:
HD 6850 Crossfire Setup total price:
$144.99 HD 6850
$99.99 Power Supply (Newegg.com - OCZ OCZ750FTY 750W ATX12V / EPS12V SLI Ready 80 PLUS BRONZE Certified Power Supply - does this look good, considering the Crossfire? I think the wattage is fine.)
= $194.99 (also, there is a -$10 MIR for the graphics card and a -$25 MIR for the PSU, so, this could be as low as $159.99)
-$100-110 from reselling old HD 6850
= $189.99-$199.99 (possible MIR of $10-$20, so, could be as low as $169.99 to $179.99)
Link to my mobo details:
Would Crossfiring on this mobo work fine or would it be a sucky idea and I should just go with the single card solution? The HD 6850 Crossfired appear to have performance that blows the GTX 570/HD 6970 out of the water, but, the benchmarks of those were run on very good PC's with newer hardware.
All benchmarks I've seen have shown the Crossfired HD 6850's would be significantly better than the GTX 570 and HD 6970, and even better than a single GTX 580 which is a monster GPU, second only to the GTX 590 of the Nvidia line, which is very impressive. I already have a HD 6850 I bought a long time ago so I think Crossfiring is the way to go. Also, my PSU I have now is getting old and is only 550W, so, I figure it might be a good bonus to replace that, too. And it turns out I might save $5.00 in the end over the other options! But, what do you guys think? Any issues with drivers I should know about? Are the benchmarks somewhat false in nature?
