With two 4850s paired up in CrossFire, we once again ran into issues with our power supply. Our 1000W OCZ EliteXStream wasn't always enough for the dual-GPU setup and in Call of Duty 4 our system rebooted in the middle of our test at 2560 x 1600. Thankfully OCZ sent us a PC Power & Cooling Turbo Cool 1200W unit that is certified for use with GeForce GTX 280 SLI, and if it works on that beast, it had better work with a pair of 4850s in CrossFire.
Wait... OCZ sent a PC Power & Cooling... aren't they TWO DIFFERENT COMPANIES??? O_o
did not include any Crossfire or SLI results, so who knows, they might be right.
Lol why does crossfire results come as a surprise? I would be surprised if they DIDNT do those.
The 9800gtx just lost 10% of its graphics performance as resources become tied up in physics. the 4850 looses about 5% .
