I have a HP Pavilion elite hpe desktop and i want to upgrade the psu and gpu to a gtx 550ti and a corsair cx600 and i want to know if both those will fit and work properly?
Here is the psu:

and the gpu:

and my specs are if needed:
i5 2500 @ 3.3ghz
440 GT
1TB HDD
6GB RAM
intel h67 motherboard

also i was looking at a gtx 560:

but it only has two dvi and i need a dvi and vga so how would that work? would a hp monitor work on the 560?
would the 560 work on this monitor?
