Hello, i have a compaq Presario CQ5300F, computer spec's: processor: AMD Sempron(tm) Processor LE-1300 2.30 Ram: 2.00 gb (1.87 gb usable) 64-bit operating system chip type: GeForce 6150SE nForce 430 what are the possible options to change my graphics card and if so, which graphics card should i get?
I would also recommend you use a 6450, especially with that power supply. It may or may not handle a 7750.
But don't get your hopes up, you're using an antique processor on an outdated platform, so you won't even be playing most modern games, let alone be seeing acceptable framerates. If you want to game you ought to upgrade your whole platform.
