I'm planning to upgrade my current rig which I've had for two years now. I'm not really concerned about anything beside the GPU as my HD 7950 is not cutting it anymore. I've done some research and got stuck with two options:
-2x Reference R9 290x
-GTX 780 TI
I'll mainly be using the PC for gaming @ 1080p, will upgrade to 1400p later on this year. Here's my current rig:
Cooler Master HAF 912
Gigabyte Z77 GA-Z77-D3H
Cooler Master V6GT
CORSAIR TX 750w V2
Intel Core i5 3570K @ 4.0
Gigabyte AMD HD 7950 @ 1000/1250
Corsair Vengeance 4x 4GB
Seagate Barracuda 2 TB
I'm somewhat concerned about two things, will my CPU be a bottleneck? I plan on waiting for intel refreshes before I upgrade the motherboard and CPU. Another thing is the PSU, will 750watts be enough for 2 290x'? According to AMD, it's rated at 250 watts but I don't want to bottleneck the GPUs, I'm even considering getting another motherboard to handle the cards better.
I thought about that, but I don't think getting another 7950 is a good idea because I want this upgrade to last me another 2 years.
I was thinking of the reference cards because I can get them somewhat cheap, around the same price as a new 780TI. I would later on get waterblocks along with the new CPU + Motherboard and run the whole thing on loops. Honestly, I can't think of a more cost effective option on the long run, except getting another 7950 now and then wait for GPU refreshes and get everything all together.
I'm kinda undecided about the R9 because it doesn't perform very well without proper cooling, and I have no idea when the CPU refreshes are gonna be so I don't want to be stuck with two incapable cards..
R9 290x sounds like the optimal solution then.
@BustaRhymes, I was comparing a single 780ti with 2 290x's. Although, my motherboard only supports x4 on the second slot so that might result in relatively worse performance. That's why I'd rather stick with single cards for now, even knowing that 2x 7950s will do me good and will not require much work.
I found two GPUs with custom coolers and acceptable price, the MSI OC version and Sapphire tri-x. I think I'll go with the cheaper of the two at this point.
just saying, the 780 ti is the most powerful single GPU on the market right now. if the extra cost of the 780ti is not an issue I would say go with that. I recommend the classified models. The 290x isn’t a bad card. Just my two cents
