I'm just using this one quote from you, but grabbing a few points from your other quotes (not listed here).

And its not about being broken or not ^^;;; Its about moving on morbid like many said.
1) Yes, doing general daily tasks IS faster in 7. Whether the XP lovers will admit it or not....its the truth. You can thank Superfetch for this.
2) Yes, it does use more RAM at idle. Again, thank Superfetch. You're actually USING your RAM instead of letting it sit there and waste away.
3) Gaming performance is roughly the same on 7 as XP (as you've found out), but you'll have the added advantage of DX10 and 11.
4) If you're going to do it, go 64bit (which I believe you already did). There haven't been ANY major compatibility issues with 64bit since Vista came out. Haters gonna hate...but Vista wasn't nearly as fail as it was made out to be. The biggest problem with it was fixed very quickly, and that was manufacturers not putting drivers out quickly enough. The other major complaint was file transfers being slow as heck...which SP1 fixed it.
5) You can easily handle a GTX460 or better with your sig rig. Just put a decent overclock on your e5200. She'll do 3.6+GHz easy
Bottom line is here, there is no reason to be using a decade old operating system with hardware that is capable of running 7. Back when Vista was out....I would say the same thing about Vista. I ran Vista exclusively since the Beta stages. The Beta and Release Candidates were CRAP for it. But the official release wasn't half bad at all. And after SP1 it was amazing.
. You are now using your rig to its fullest potential by actually USING your 4GB of RAM, and the full features of your GPU. You made a good choice by making the switch.
