Sweet. MBP. 8GB RAM.
Recently decided to purchase some RAM upgrades for my laptop. It's not that it wasn't that fast with 4GB, but when using a 2GB RAM windows 7 VM (VMware Fusion), things started to slow down. I still need to use windows in a VM for software applications like QuickBooks, and to access the KVM switch we have out in Buffalo. I purchased the upgrade from Other World Computing, aka macsales.com, where it was only about $130 for the upgrade. It was slightly higher than newegg, but OWC had the video card upgrade for my Mac Pro (A whole different fiasco). Anyways, the laptop is running lightning fast 
Windows 7 slower than Vista?
Well I've been working on my article for Windows 7 x64 vs Vista x64 on my new Quad-Core budget PC that I built for some home gaming, and I just started doing the benchmarks for Windows 7 in overclocked form. I must say... I'm extremely surprised that I'm not seeing the same results that everyone else is seeing.
I thought that when I was doing the comparison at stock speeds, I would see a bigger difference once I overclocked, but even now, it is pretty much the same and even slower in some cases.
If I had to take a guess as to what is going on, I'd say that there are still some driver issues to be worked out. The parts are all pretty new parts, but I was able to install all of the drivers in Windows 7 without a problem.
Anyways, it looks like I might end up choosing Vista to run on my home PC. I'm itchin to start playing some CS:S, Crysis and World in Conflict.
Just finished my HOWTO on Windows 7
Check out the article I just finished... It's a HOWTO on installing and configuring Windows 7 x64 in VMWare Fusion, which is VMWare's workstation product for Mac OS X.

I've had it running on my 8-Core Mac Pro for a little while now
