Hey all. I am tired of waiting for the new MBP's to be released, and am pretty sure I am just going to buy a refurb this week. My question is that there is a MBP 15-inch with 2.2GHz processor for $1,699, and then there is a 2.4GHz processor one for $2,099. The only difference besides this minor speed-bump is the video card and 40 gigs of extra hard drive, which I could live without. The 2.2 one has a "NVIDIA GeForce 8600M GT with 128MB of GDDR3 memory", and the 2.4 one has a "NVIDIA GeForce 8600M GT with 256MB of GDDR3 memory". Is the 256mb card worth the extra $400? I don't do much graphically, but I do play WoW pretty regularly, so I am willing to pay the extra $400 if it is going to make a noticeable difference, same for the processor bump, but I figured that wasn't really worth $400 just for such a small upgrade in the processor. Any help is much appreciated, thanks a lot.
