Am I CPU limiting myself?

[matt_fsr]

OK, so it's been a little while since my last upgrade which was from a C2D setup to a i3 540 3.06Ghz , which is quite happy pottering along at 4.4Ghz under air.

My question is, am I likely to be CPU limiting myself for anything?? The PC is primarily a gaming rig, I've no great interest in performance for other tasks at all.

Also, would I be limiting myself if I upgraded from my existing GTX460 768Mb card? I'm normally an nVidia fan, but it seems like ATi have the best bang-for-buck in the ~£200 gfx sector, which is normally where I tend to spend monies.

Advice pls?

Very tempted on slapping this in my PC, while its on offer.

Games I play, and have still to play are:

Total War; NTW with Darthmod and Shogun 2 (+expansion) still to play.
Metro 2033 still to play.
Skyrim - with mods and HD textures.
Payday: The Heist and Killing Floor, though these are less demanding.

Also going to be looking at Company of Heroes 2 and Rome Total War 2 when they're out.
