Old processor and DDR2 ram, you will not like it with Windows 7, it will be slow and 5770 will not help. Mobo is very old too, no upgrades possible.

Get something modern instead, not on ebay:I want to get a gaming computer for games like skyrim and battlefield 3 when they come out, would this be good?
Computer Case : Should be fine

Power Supply Upgrade : Fine

Motherboard : See processor

DDR2 Memory : Enough ram but DDR2 which is old, try getting 4gb of DDR3 instead

Processor : Old processor, only dual core you want to go for something with quad core in this age, go for an i5 or i7 if you can afford

CPU Cooling Fan : Fine

Hard Drive : Fine

Video Card : Fine, probably the minimum you would want, HD5850 is recommended for Skyrim but not required

You're probably paying twice as much as if you bought those components separately and assembled them yourself.

I guess you have a monitor, speakers, keyboard and mouse already?

All my parts came with warranties so that isn't an issue, and would you rather send one part back than the whole thing if it came to that?

Also, I've heard horror stories about people trying to play games with Windows 7 64 bit.

But to answer your question, it looks fine. I have about the same system and can play anything on its highest settings.
