I recently scored a deal on a Gateway with a 300-watt PSU, and 1TB HDD. It also has a Phenom 9500 (I know, I've heard a lot of hate about it) and a Radeon HD 2400xt. My problem is that I should be able to smoothly play NFS Shift on lowest settings at 800x600, but it is so laggy, on Windows 7 and Vista. I need to know if there's anything that I can do to make this thing perform better?? I know I need a new GFX card, but I'm not willing to spend much more than $100. I also know that having a 300-watt PSU is a problem. Would I be able to power a GeForce 9800 GT with my PSU? It does have a 6-Pin power connector, and I was looking at something along the lines of these:

Which one should I feel comfortable putting in my box? I see that two of them say no extra power req's, and one of them says 6-pin. I don't want to get one that I will have to send back.
Also, I know everyone says how bad Phenom 1's are at overclocking, but is there any way i could get it up to 2.4 or 2.5 with software? Any other way i could inexpensively boost my performance?
