Ok... With these 2 build the rest of the system would look like this:
4GB Patriot 1333MHz CL9 ( 1x4 )
Cooler Master Elite 430
Hitachi 160GB sata2 ( reused )
Now, if i compromised a little, say...
PSU to Chieftec CFT-600-14cs ( every single person recommends me this PSU, even a Serbian PC newspaper said it would be a great choice )
i would be able to afford this combo:
MSI Twin Frozr II GTX 560 Ti
and i wouldn't upgrade anything. What do you think?
