You're forgetting if you're out of B.C. you pay 5% tax to NCIX. Or you pay 13% to egg regardless of where you live. That's the only incentive for me to shop at ncix. After July, 2010, this incentive will be gone. Read HST.
2 gigs are kinda low by today's standard. If you run Vista/7 basic, it's ok. For Aero, your best bet is 4 gigs.
If you plan to use the IGP (onboard gpu), it's a good buy. Otherwise, look for a full-size ATX with no IGP like Gigabyte GA-MA770-UD3. Then throw in your discreet gpu.
I've been waiting for a deal on the 620 + AM2+/3 mobo for reusing my ddr2 on a family pc. It's been months. I don't see any deals. The $8 shipping this week is for $100+ order. Not incentive enough to make me upgrade the family pc to quad. I think I missed out the ~$225 Phenom x4 940 + mobo. The mobo was practically $40. Regular price $100+.
