So i finally got around to getting my old X2 3800+ up and running. Now that it is working I want better gfx than a Geforce 6150LE. I plan to buy a PSU but atm its a generic 350w. I'm looking to spend not too much cash ( yea i know budget cards ) and am wondering what Nvidia has to offer performance wise compared to a HD 6450. I would also like something that doesnt need a aux power connector as the craptacular PSU prolly couldn't handle it. Advice and comments appreciated I think i will prolly get the PSU first, but still need advice on a card suitable for a system of this age.
