Me and a friend of mine will both be building similar computers (my friend's will probably be a rough clone of mine). We're looking for good overall performance, especially in gaming. Being in Canada, some parts have different availability or princing than in the states.
HSF: Undecided. newegg.ca has a lot less choice heatsinkwise than the american counterpart, and I'm honestly not sure what to get that I could use on a 1156 socket.
A few questions I have: How much does the video card manufacturer affect it? The 5870s are slowly becoming available on newegg.ca, and some manufacturers have yet to appear in the list (like XFX). I'm assuming it'll be the same for the 5850. Any manufacturers to AVOID? Should I bother waiting for different manufacturers, or are most OK enough?
Also, how are the motherboard, PSU and case choices? I've read of a lot of other people going for the P7P55D PRO, and it seems good for me. The PSU seems good as it is modular, 80plus certified and has a high wattage (more upgrade-ready). Finally, the case seemed like a reasonable deal to me, but how does it go against Antec 300 or Antec 900?
Finally, I'm not sure what to do about the CPU heatsink. I've looked, and there's a lot less choice in Canada. Also, since 1156 is a newer socket, there aren't many (or any on newegg) heatsinks with the proper bracket. What are others doing about their i7 860 heatsink?
