November 30, 200916 yr Anyone using this card for FSX yet?? If so whats it like?? Im getting a pair with EVGA X58 Classified , I7 920.Can't wait to fire it upCheers Chris
November 30, 200916 yr It is so hard to find one, probably you will be the first, so please post your impressions and results.
November 30, 200916 yr You're getting 2 5970's? Why? There's not a game on the planet that will take advantage of that much GPU horsepower.
December 1, 200916 yr Author You're getting 2 5970's? Why? There's not a game on the planet that will take advantage of that much GPU horsepower. Yes big over kill but this is my last upgrade for a while so going all out. Yep will let you know how it all goes. CD
December 1, 200916 yr Multi-GPU performance scaling decreases on a per-GPU basis. i.e., the more GPUs you have, the less you gain. 2x 5970s means 4 GPUs. The reason for this is it becomes increasingly difficult to split a workload across multiple GPUs as you add them. The biggest bottleneck here is the interface, which has to carry data to each GPU to give it something to do, then send the results back to the "master" card's display output chip. That's a lot of data flying around the system, more than any standard interface was designed to handle. That's why the dual GPU cards have dedicated I/O chips which transfer data between the two onboard GPUs. Bottom line: the performance you'll gain going from 1x 5970 to 2x is virtually nil, unless you plan on running a display wall @ some insane resolution like 7680x3200 with SSAA. Basically you're just adding complexity and that causes bugs. Lots of games actually perform worse with 4 GPUs than 2.
