You should have noted that in the OP. The GT120 (and 130) are rather disappointing video cards IMO. If you want a refurb, get a 21.5" with the 4670 when it comes up although for what you are doing, it won't make much of a difference although HD2600 > 9400m would be a downgrade.
Okay, thanks. I think I might just get the 21.5" refurb since it's the same price as a 24" refurb.
Thanks everyone!
