To be perfectly honest a single core Athlon 3500+ is going to chock any modern graphics card, not to mention any CPU intensive game. I really think your money would be better spent saving for a complete system overhaul.
Most modern games are multi-threaded and even list a dual core in the minimum requirements. Even if you did install a lower end gaming card, the rest of your system is going to hold you back.
I have been looking into upgrading my CPU. The problem is that I have a Socket 939 motherboard which most likely will not recognize any dual core processors, as far as I know.
Also, the BIOS chip I have is made custom to my pc and there is no option for upgrade.
I could probably install a slightly better CPU but I don't know if that would help much. If I'm wrong about any of this, let me know. I don't really want to start from scratch and have to buy parts for a whole new PC but it looks like that may be my only option.
Wiiinppongamer is about right on the 4650. That is probably the most I would go with on your current system to maybe sqeeze a little life out of it yet. But I wouldn't expect magical things to happen.
PC gaming isn't really a cheap hobby. That is why so many are going to the console. I just can't give up my FPS and RTS's to a controller. There is no way I would be satisfied trying to get crosshairs on someones head with an analog stick. Granted I do love fighting and racing games on a console.
Nope, he just said that he suggests to stay with the manufacturer of your integrated chipset for whatever reason.
I wouldn't agree with this, but he definitely did not say to stick with integrated.
Go read it again.
How much were you going to spend on a new graphics card/PSU?
