hes not OCing yet, and he will soon. and when he does he will get more out of the Opty 165. and for now i dont think he will need to worry about how the OPty 165 will handle games cause 1.8GHz still is above the Recommended Speed, plus a good Video Card and Ram he'll be good with the 1.8GHz for a couple of months then he can OC it to high speeds, and the 4400 X2 isnt that great a OCer, not better than the opty neways.
And for monitor, since you live in Canada anyways, but im not sure wer u live, if its Ontario then go with this......
thats the one im getting, if not try to find one were you live, otherwise, try to find a Monitor thats both 19", under or equal to $400 and less than 8ms respons time. i did, im sure you'll have no trouble depending on where u live.
