System Upgrade Time


In Runtime

I'm going off to uni in a few months and I'm thinking about buying a nice new fresh system or maybe just some tweaks

Here is my main system:

Q6700 - with Artic Freezer Pro
2x 2GB + 2x 1GB OCZ DDRII 800MHz (I think) RAM = 6GB Total
Asrock penryn1600sli
EN8800GT 512MB
A few HDDs.

Now my first question is

My gfx card is apparently capable of PCIE 2.0 but my mobo has only 1.0s. Would I notice a difference if I upgraded to a PCIE 2.0 system? Any suggestions?

Thinking about going to AMD. I currently has a Q6700 on stock (I should OC), but seen a HEX core for

Programming, Photoshop, SPICE analysis, MATLAB - image processing
I play a few games - thought haven't played in a while (BF1942, BF2, BC2, source stuff, COH, RO and enjoy a good single player game once in a while).

I know there is quite a few tweaks I can do with my system and I need to find the time to mess around with it, but what enhancements would you make if you had my system.

I'll probs get a another TB and external enclosure. Don't think it's worth the GB/£ for SSD yet.
