For $499 this is EXACTLY what I'm looking for (15 or 17 inch, i5 or i7, discrete graphics) but it shows up as $549 for me. Resolution isn't an issue for me. I'm quite used to the 1280x800 on my 3.5 year old Acer Extensa 5230E. 1366x768 is bigger enough but 1600x900 would be better, so I think I will hold out for the 17 inch, Core i7 version with GT650m, currently listed at $749
GT630M is great, but GT650M has about double the power. It pairs well with a quad core i7 3rd gen. I have $600 saved specific to a new laptop and maybe that one will drop to $699 about the time I have $700ish to spend. If not, the $549 one at $499 is a good deal and it would leave me some cash to pick up an SSD. Some V3 series Aspires have two drive bays, after all. The 17 inch ones for sure.
If you want a higher res like 1600x900, are ok with Core i5, and still need discrete graphics, this $649 one might suit your needs and may come up $599 during the next sale:
If you care about the graphics card and are going to spend $650, you may want to look into 6622:
