- Why Intel -
Intel's C2D is the best CPU available at the moment AND it overclocks like crazy.
- Would this be any better (seems to have a very fast clock speed) - AMD X2 6000+ -
Nah the E6600 will beat it at most things and that's even before you consider overclocking.
- Or this one even ~ E6750 -
Wasted money if you're overclocking... unless you're waiting for the infamous price cuts.
- Why Nvidia -
The 8800GTS is the best bang for buck card around at the moment.
- Since i will mainly use my computer for gaming would it be worthwhile investing in a larger memory GPU or something like a HD2900XT -
Probably not, the GTS will laugh at everything you throw at it in 1280x1024.
- Why not PC6400 memory -
If you're overclocking I'd say go with PC6400 actually.
- Why does the PSU have to be so expensive -
Cos a cheap PSU = explosion =
- Those heat sinks seem pretty big and heavy, how secure are they
-
Secure enough, just don't transport your case with them in.
