Can I use Radeon 7770 on this computer

[pakhavit]

Hi everyone.

I'm have zero knowledge of computer and laptop so I need help with upgrading my game FPS

Right now I have Gateway SX2370-UR30P. Quad A6-3600 APU with Radeon HD6530D
It works fine with low setting in GW2 / Tera at 20 FPS, but recently my girlfriend is enjoying playing
MMORPG with me. So I want to buy her something so she can play a game at high fps with high setting.

We're playing Tera online/ GW 2 on low setting right now with only 15 fps. I want to play on Medium setting or high for 25-30fps.

I have a lot questions to ask because I think there's a lot of thing I need to change

1. Will Radeon HD 6570 DDR3 make the game run mid setting?
2. Should I buy Radeon HD 7770 and new PSU instead of HD 6570?
3. Do I need to upgrade 4gb DDR3 memory? It said DDR5 on Radeon HD 7770, I don't knowwhat it means.

4. Based on Neweeg power supply calculator, I only need 280 WAT to run this computer with Radeon HD 7770.
How much watt do I need for PSU 450? 500?



Thank you very much

EDIT: Case is not a problem, I will move everything to my old computer case

It doesn't have two GPUs--only one that is integrated into the CPU.

You can try a new graphics card, but you have to make sure your PSU is up to scratch.
