Wow, thank you very much! But wont it have any problem that the PSU in my computer is pretty weak?
Here is the power supply information: Peak 400 W (PFC)
can it run the GTX 560ti or the ASUS 7850?
EDIT: I found out that it doesnt support any of those, so im buying a new PSU... Im going to have a hard time trying to discover a good compatible one! hahaha, if anyone can help it would be great!
