What version of Windows are you running? If Windows 7 or Vista, look at your performance index (click Start, right-click Computer, and click Properties). 32 or 64 bit version? What do you have for graphics? If you're using integrated graphics, add a discrete video card. If you have a 64 bit OS, add more RAM. If you're running XP or older, consider upgrading to Windows 7.
I'm not sure what I should upgrade on my PC first: my motherboard or my processor(s).
I'm running an AMD Phenom 9600 quad-core 2.3 GHz and my motherboard is... well, I think it's a BIOSTAR N61PB-M2S (PCI-Express).
I was told elsewhere at some point that I'd have to upgrade both my processor and motherboard at the same time for some reason, any thoughts? Furthermore, any relatively non-pricey upgrade suggestions?
Elsewhere I've got three, nearly four gigs of RAM and a Geforce GTX 460, both of which I just recently upgraded to, and I'm still having a lot of trouble running games, I'm wondering what's left keeping it down.
