I have an old Dell 8300 with a XFX HD 4650 agp video card, 2.5 gigs of ram, P4 @3.0ghz and a 400w psu w/ Windows 7
I'm not looking to buy a whole new rig because mine is still running fine and I'm not confident that I'll buy all the correct/compatible parts if I build my own
Although I am looking to upgrade my system as far as possible. I definitely want to upgrade my RAM a bit and video card so recommendations are welcome. My PC only takes AGP cards btw and I don't have a price range.
I agree with swifty_morgan on this one, any money spent on this system with hopes of even a modest performance gain that you might notice is money in the toilet.
Save your cash for a complete platform upgrade.
