I really dont know which brand makes a good processor.
I'm running now a:

core2duo e7500 2.93ghz 3mb L2 cache
ECS g31
I3d 9500gt 1gb 128bit ddr2 PCI-e
2gb Apacer 667 ddr2
160gb Sata HDD
17" LCD monitor

I'm into gaming and media editing(photoshop, aftereffects)

Do you think it would be better for me to upgrade my procie and mobo with an
AMD Phenom x4 9650 2.3ghz 2mb L2 cache, still with the same pc specs?

would I notice the difference?

I am not really satisfied with my core2duo procie, cuz NBA 2k9 won't even run smoothly, but my friend's computer (AMD athlon64 x2 2.6, with the same pc specs as mine but lower ram, only 1gb) runs nba 2k9 much smoother than my PC.

I really dont know how come it's like that.

Seeing the difference,
it made me to see that AMD's early version of dual core's are better than Intel's Newest versions of Dual Cores(namely core2duo's).

Guyz, please help me decide if I'm gonna upgrade my processor or just tweak it.

Thankz!!!
