Hello guys, Im from Singapore and i wanted to build my 1st Gaming PC and I need some advice from you guys.
I went to a IT mall in singapore is called ''Simlim mall'' and they gave me a specs,

Kingston 8GB Ram
Hitachi 1TB HDD
AMD Radeon HD 6790 1GB
500Watts PowerSupply (I forgoten to ask what brand isit.)
Windows 7 Home Premium 64bit
DVD-RW
Total Cost of $1000(sgd).

The games that Im going to play will be, Call of Duty, Black Ops, Crysis 2, Battlefield 2, DeadSpace, In the future Battlefield 3.

So I need some advice..
Do I have to change my processer to I7? And is processer importen for Gaming?
Is Asrock H61 a good Motherboard? Or do i have to change to Asus?
Is my Graphic card good enough to support all those games with high resolution and full settings with no spikes/lag?
Is my 500watts good enough to support everything? Or do i have to change to a higher Watts?

This is my first time post'ing a Thread in a forum.. Sorry for my poor english.

That's a rip off, you can build a much better system for that price.

Do you know of any online computer stores where you can buy parts? All you would have to do is assemble the computer and install windows.

Will you overclock your machine? If yes, consider i5 2500k with Z68 motherboard. If not, consider i5 2400
PSU - You have to find out the brand.

Yes I will overclock. But with the specs I have can I play Crysis 2 and Battlefield 2/3 with high resolution, Full settings and no spike no lag?
What if i stay with Asrock H61 motherboard will it affect my computer speed?

i don't think the 6790 can max crysis 2 on a high res and high shaders, and i doubt it will get near that on bf3, it'll do fine but not the res and shading.
