As for the video card and psu I have a friend who has a spare of both and willing to give them to me for free. The card is a ATI Radeon HD 5870 and i'm not sure which psu he has but it's 700w so it should be more than enough for what I need.
I'm a little concerned over my parts since my video card is an older model, are my mobo and cpu too powerful? I'd like to have the option to upgrade in the future but that's probably pretty far off from now.
As for other information, I am not buying a monitor and my native resolution is 1920x1080 and as the title states this is mainly for gaming.
That motherboard and CPU aren't compatible. You also don't really want an 8 core FX series cpu as it will be stomped by a run of the mill i5.
I changed the cpu. I asked the AMD forum the other day and their consensus was that the card can handle 1080p just fine. I'm not looking to have max settings for every thing and the card seems to be enough to play high on most games. If anything i can replace it after building if it isn't as good as i thought it would be as it's free, i have nothing to lose.
