a DUAL QUAD CORE,  if that's what you have, is not an out of date machine at all! 
there's dual core (somewhat older)
Quad core (recent)
two quad cores (Xeons, very VERY expensive)
and the new i7 CPUs which are like, two quad cores ad will replace normal quad cores.

Actually the latest Nvidia driver made my system worse and I had to do a system restore today, lol!

FOr latest Nvidia video drivers, know what type your video card is, then go to
http://www.nvidia.com/Download/index.aspx?lang=en-us
Select drivers form the menus for your operating system, and graphics card type (very bad if you put in wrong ones)

download, install driver. I think the prior version I have for my system is better than the newest one (which made my mouse lock up! jeesh)

if it goes bad, you do a System Restore to undo it.

Drivers are bits of software that tell hardware how to work. over time they get improved, bugs removed etc.

Sounds like your system is recent, so shouldn't need to upgrade the hardware.

However a 64 bit operating system is better, but you'd need ot buy a new copy of WIndows specifically for that, and re-install everything which maybe a pain in the arse to do.

Have you run WIndows Update to get drivers for your system?

I get PCs specifically built to order in locla shop, so I KNOW what is inside and choose the best parts within my budget.

Cobra,
yeah yah yeah,...yawn.
works fine on my system, just minor bugs, odd that, eh? :rolleyes:
yes some poor sods have problems, but, apart form MACs, often the cause of severe problems is a crappy PC, due to bad make, or drivers not updated, or loaded with malware, games (with DRM crud) etc,and Murphy's Law can hit anyone.
