Oh well for gaming you will want to change that vid card for sure. You should get a 5770 at the very least and AMD is launching new cards this week so I would probably just wait a week and you could probably get the same card cheaper or a newer or better card for the same price. Depending on what resolution of gaming you want to play at a 5770, 5830, gt460, or whatever the 6000s in that range would be pretty good cards. And I would probably choose some better ram that is cl7 or cl8 as javamonsoon pointed out. And again I would checkout the best builds for $1000 dollars which given that is your budget would give you multiple reference builds to customize for yourself.
