Graphics Card Upgrade

[Khiem Nguyen]

Hello,

I bought my PC exactly 2 years ago. I think it's time to upgrade my VGA because it doesn't work quite well currently as the gaming requirements are higher and higher...

So my current rig:
1. CPU: intel core i5 3470 Ivy Bridge
2. Main: MSI B75A-G43
3. RAM: 2x 4GB DDR3 667Mhz Corsair
4. VGA: AMD Radeon HD7790 1GB
5. PSU: Corsair VS550
6. Storage: 2x 1TB HDD 7200rpm
7. Display: DELL U2312HM

I want to replace the current VGA HD7790. I'm wondering between GTX970 and R9 390 (not X). So could you guys advise me 2 things?
1. Which one is better with my current setup (of course I spent hours of researching - generally the R9 390 is better but I don't have a 4K display here, so is this still better?)
2. Can my PSU endure one of the above VGA? (GTX970 or R9 390)
2.1. If I need to replace my PSU, what is a viable option?

Any input is appreciated. Thank you guys very much.

You won't have to replace your PSU if you go with the GTX 970. And it trades punches with the R9-390 depending on the game. Basically, it is as fast as the 390 but uses half the watts. http://gpu.userbenchmark.com/Compare/Nvidia-GTX-970-vs-AMD-R9-390/2577vs3481
