What do you define as stable? Can you run prime95 without crashing?

Yes I am able. When I first started overclocking the machine I kept trying for 3.5 but stressing with prime95 forced me to stop at 3.4.
The system has handled everything involving multitasking and heavy gaming wonderfully. The only instability I have run into was during the summer and having to crank up the fan on the GPU from default 45% to 75%.

I've got a 7750BE sitting in an ASRock A780GMH/128M. Runs stable at 3.1Ghz, CPU-Z validation here:

Just the one in the back of the case and the PSU, CPU, and CPU fans. The 7750 pulls 95W, and my GPU wants 350 minimum. I don't think 100W is a lot of wiggle room for hardware, and the fans are pulling too many amps.

I'm gonna be upgrading to an Athlon II and a 1000W PSU soon, so I'll be good.

Your PSU is fine. There's no way that 8800 actually pulls close to 350w. That might just be a recommended PSU wattage for the card, it will NEVER pull that, or come remotely close. You getting a 1000w is insane.

Well my temps rise and my PC locks up when I connect more than one case fan. My PSU isn't putting out enough of something. Plus, I plan on getting the Athlon II 250 and a new mobo, and eventually a GTX285, so a 1000W will give me some upgrade room.

A solid 750w would give you enough headroom, I'm just saying 1000w is THAT overkill.

Even with all the parts you listed, a solid 650, like the Corsair TX650, would do just fine with that setup. If you were planning on going SLi in the future, then up to the 750.

cavi has a point 750 is enoghf juice for SLi set up , but then againe ur 550 could be worn out and tierd but thier s alsow another thing a cheap psu even 550 dosent mean thats its 550 it means that it will max out at 550 and only ran at 550 for a short time some have a heavy duty 550 clasification those will run at thier max wattege all day .

and the sugested psu for the vid card 350 means that ur vid card dosent take 350 but it means that a computer runing 1hd 1cd 2 fans a mobo and ur vid card will need about 350w to live .

buying a psu i usualy goo for the one that is heavy literly heavy like a brick if u pick it up and it feels like thier nothing more then a fan and a few wires then its probly cheap and wont do really well in the long run a heavy psu means it has nice big cooling fins inside and its built to last

if u set ur mind on a 1000w psu then go for the one that has the most 6 pin vid card plugs 8 pin mobo plugs and some new plugs that u havent seen before usualy a good sing that it will be future proof

Well my point is, a PSU is something you can buy the best of and not worry about it being outdated by next week, so why would I buy two different PSUs when I need to upgrade, instead of one mammoth now?
