[Solved] New Kids PC

So my son (9 yo) wants a new PC. His old one died. It was my old Opteron 152/Gigabyte K8N system. Anyway, I am reusing the case, fans, optical and floppy drive. I Bought a Foxconn C51XEM2AA AM2 motherboard, x2 6000+ CPU and 4GB of Corsair DDR2-800 for $100 from a buddy. I already have a Zalman 9700NT heatsink he can use and a Corsair 550vx PSU I bought and never put to use. I will have to buy a Hard Drive and Video card.
A co-worker has 2 9600GT's he just pulled out of his s775 system to part out and sell. He's building a new 1366/i7 system.........
I know this sounds like overkill for a kid but $80 for the pair is cheaper than buying 1 card. Will the 6000+ be enough for 2 9600GT's in SLI? He has my old 21" ASUS VH222H which runs at 1920 x 1080 res.
This just feels hard to pass up. I could have him up & running for $250.00.........plus an OS which I forgot about 'till now

What would you do? Any other ideas?

Yeah, your kid doesn't know if he got a great machine on his hand...
Go for it...

Thanks to all of you. I just bought the cards and he threw in a 250GB Seagate 7200.10 SATA hard Drive he never used! He has been using the cards for about 6 months. He bought them on clearance after his 8800GTX died. They are Palit Super 9600GT 1GB dual slot cards with rear cooling vents. Pretty nice looking and it became a great deal really. I have $180 out of my pocket right now and nearly a system with all the parts I had and am reusing. I am happy about that. A copy of Windows 7 and he'll be set, for a while anyway.


Thanks again to you all for the advice!!

CPU bottleneck depends on the game you play.

There will be no bottleneck if you'll be playing Burnout Paradise on max...
But the CPU may bottleneck while playing a Buggy game like GTA4.

But you can OC anyway.

You can try Crysis.
It will be GPU bottleneck in your case,Not CPU bottlenecked...
