New graphics card...on a budget! Suggestions?

All right...so, I wasted money for my first computer on a laptop when I started college. That was a mistake, but I learned from it, and built a computer my second year...again, making mistakes, as I wasn't quite privy to this whole performance-based world...

Well, now, I'm stuck with a P4 system (3.3GHz) and a Radeon x800 GTO, which works great for shader model 2.0 games...but not so much for newer stuff.

I recently upgraded my motherboard to an MSI P965 Neo-F, so I have some interesting choices to make in my upgrades.

Oh, and MSI motherboards have about the worst english I've ever seen on some of their screens.

The main question:

Of these three routes, which is the best to go?

1)8600 GT + E4300 for around $250
2)E6600
3)8800GTS 320 MB version

they all cost about the same...so which would I be most satisfied with. Would the new processor really bump my frame rate with an x800GTO? Would the 8800GTS stall out because of my Prescott 630 P4? Does spending less on both mean better framerates and faster load times?

I know you said you are on a tight budget but really if it was me i would save a bit more and try for a processor and g/card.
To answer your questions.

1 Crap card /brilliant and i cant stress how good of an overclocable cpu.
2 dont really think you will get the kind of diff you are looking for as the gto is fast ok its sm2 but its still fast(have you tryed unlocking or ocing it)theese cards are pretty good at this also.
3 Probably the best compramise card /value /performance at the min only my opinion though, its a fast dx9 card which will play some dx10 stuff well enough but dont think of it as a long term dx10 solution as it isnt.
4 Have you def decided that if you get a new graphics card it has to be dx10 conpatable because in your position i would get (depending on your budget as im in england and our pricing is different)either a 1950pro/xt and the E4300.
That gives you a fast dx9 card and a fast if you oc it processor

You could try returning that mobo and get a am2 one and this http://www.newegg.com/Product/Prod [...] 6819103774
and this 8800gts http://www.newegg.com/Product/Prod [...] 814130082.
And you are just over 300 dollars sorry for this suggestion but it was the single way of getting an 8800gts and a good dual core cpu to run it, plus the cpu oc's very well.
