P7450 vs t6500 again

[Guest]

Dear all!
I am seeking advice on which of these 2 laptop configurations to go for. I would primarily use it for working with graphic software like adobe CS, and maybe some gaming.
they are:
Dell Inspiron
Core2Duo T6500 (2100)
6144 MB RAM
320 GB HDD
17,3" HD TL (1600x900)
DVDRW /-
512 MB ATI Radeon HD 4330

versus a Sony Vaio:
Core2Duo P7450 (2130)
4096 MB RAM
500 GB HDD
15,5" HD (1366x768)
DVDRW /- DL/Ram
512 MB ATI Mob.Radeon HD 4570

Thanks in advance for your advice!
I know one is 17" the other 15" but as they both have advantages/disadvantages, screen size is not as important as general performance.

I'd go for the VAIO, since it has a more powerful video card. Both are running a 64-bit version of Windows 7?
