is this computer even upgradeable much?

[chris14000]

specs:

2gb ddr2 667mhz ram
320gb hdd
ASUS MV2
400 W PSU
8600GTS
AMD X2 5600+
LARGE CASE
1 optical drive

with 3 spaces free


if i was to upgrade this im pretty sure i would need a better PSU as the one the computer came with is very stable but i have no idea what brand it is, also is it even worth upgrading this computer just yet?

budget £300 on upgrades the case is large so no worrys their i took a look inside and the motherboard is in 1 corner with like 2/3 of the case empty lol

i didnt want to make a double topic so ill ask my question here is this 3dmark 05 score average for my 11,650 3d marks this is in the 05 edition though cant afford 06 just yet

ok thx guys ill guess ill hold off for a while until a few price drops


anyone got any answers for my other question?

11,621 3d marks in 05 this is correct for my system yes/no?
