Help on my i5 build[buying on monday]

I pretty much asked for advice to my build last June, it ended up that I waited for the new graphic cards series and the i5 to come out this month, guess it was wise to be patient after all!

I will most likely buy my parts this monday, so I'd like to have your opinion on what I am about to purchase.

APPROXIMATE PURCHASE DATE: This Monday BUDGET RANGE: Roughly around a 900$ sub-total, no more than 1000.

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Mainly Photoshop Editing, C++ Programming, Gaming, Multitasking

PARTS NOT REQUIRED: I already bought the case(Cooler Master CM 690) and I luckily got a hard drive for free(Western Digital Caviar Blue 500GB). I will continue using my current Mouse, Keyboard, Monitor and OS

PREFERRED WEBSITE(S) FOR PARTS: I am getting my parts from NCIX My dad accepted to get my parts through ground shipping. Are there any other good computer store in Montreal I could check out?
PARTS PREFERENCES: None particuraly

OVERCLOCKING: Not yet, but later
SLI OR CROSSFIRE: Not at the moment.

MONITOR RESOLUTION: 1680x1050

ADDITIONAL COMMENTS: Not really.

Are there any reccommendation for a good CPU heatsink fan for the socket 1156?
And any possibilities to make this build a bit more powerful for much less money?
Thanks for all your help!
