Hi, I'm wondering if I upgrade my GPU, will my CPU be a performance killer or will it handle just fine in combination with a GTX 780 or AMD R9 290x?

Also will my PSU be powerfull enough? I'm planning on adding [2x] Corsair Air Series AF120 LED Quiet Edition for case ventication and a Cooler Master Hyper 212 EVO for the CPU.

My current PC setup is:
Processor: Intel I7-2600k - 3.40 GHz
Memory: Corsair Vengeance LP CML8GX3M2A1600C9 8,00 GB
Hard Drive: Plextor PX-256M5S 256GB
Motherboard: MSI P67A-GD53
Operating System: MS Windows 7 Ultimate 64-bit
Video Card: EVGA GTX 580
PSU: Cooler Master Real Power M620
Case: Corsair Carbide 200R Closed

firstly, there will be no bottleneck (performance killer) with your CPU and GPU, your CPU is still quite strong to todays standards. So in short you can handle the R9 290X or GTX 780.

The R9 290X is 50 watts more hungry, so it can run off a 620 watt PSU but it depends on the type of PSU, could you list what PSU it is as the watts isn't everything. The 780 is more power efficient, though i would not call 250Watt a good and efficient card.

Your motherboard can also handle both cards, as it has a PCI-E X16 slot, best for the cards.

All in all, if the PSU is fine, the best choice is a R9 290X (custom cooled that is), as it does perform better as a whole and is an extremely strong card.

For the price of the R9 290, it is far better value...

For the price of the R9 290, it is far better value then the R9 290X, the difference is like a GTX 780 to the titan, though forgetting about Vram, it's just clocked a little less and has a few cores cut out, if your looking at saving, the R9 290 would be a better choice, if you like best, R9 290X it is (I have one also), or even a GTX 780 Ti.

custom cooled meaning not stock (AMD stock cooled), best to get Asus DCUII / MSI Twin Frozr or lightning (best one available) / Gigabyte Windforce 3x / Sapphire Tri-X custom cooled models, which will keep the temps below 70 degrees max, if you get the stock, the temps will hit 94 degrees celsius, that is really hot but stated "within operating temperature" by AMD, which no-one could say that those temps are reasonable.

Yea I was looking at the Sapphire Tri-X or the MSI Twin Frozr or lightning.
My current GPU sometimes hits 80 ~ 90 degrees celsius which makes my fans make so much noise.

Ah GTX 780ti is a bit to expensive for my taste but ofcourse would be a great investment.
Not sure how to choose, I like the nvidia Shadow Play but will I use it a lot..
Price/performance wise AMD is the way to go I guess :)

Although the ones you mentioned are only € 60 ~ € 100 less expensive then a GTX 780 Ti

Wider memory bus 512-bit on the R9 290X compared to the 384-bit on the GTX 780Ti

4GB GDDR5 Memory, which the GX 780Ti has 3GB, the extra 1GB can help a lot, trust me

has 12 more ROPS @ 64

Higher memory clock speed

Higher pixel rate.

Though The GTX 780Ti has more to offer as well, these are my reasons to go for the R9 290X, the extra 1GB Vram is the main one.

My main concern is the heat production and fan noise.
More heat means more fan noise when spinning up right?
And reading th GTX 780 ti is cooler, but of course not sure about the MSI 290x lightning temps at full load.

Thanks again for the reply :)
But for €15 more I think i'll go with the MSI GeForce GTX 780 Ti Gaming 3GB

I guess I will be future proof for a couple of years. Not going to play on 4K res any time soon.
