upgrading to 2x gtx 670 4gb's - need advice on current setup

[JDD]

So heres my current build, am looking for any advice opinions on it.

i7 950 @ 4ghz

EVGA x58 sli 3

12gb Patriot 1333 (4gb)

2tb seagate barracuda 7200

Cooler master silent pro 1000w

haf x 932 + H100

Currently have 2 EVGA gtx 460's 1gb in sli

Upgrading to 2 EVGA gtx 670 sc 4gb (pre-ordered)

1. Will anything be bottlenecking the 2 670s?

2. Will the pci-e x16 x8 x8 reduce performance (noticeably) in sli w/ the 670's?

3. Will I be able to upgrade to 3 way 670's with this current configuration or is that pushing it lol?

Thanks in advance!

1. Will anything be bottlenecking the 2 670s? No, you should not have any problems with this system

2. Will the pci-e x16 x8 x8 reduce performance (noticeably) in sli w/ the 670's? You will not see any noticeable performance issues.

3. Will I be able to upgrade to 3 way 670's with this current configuration or is that pushing it lol? Yes, you should be able to run 3 way SLI.

So far there is not indication that the PCI 3 performance will suffer when running in PCI 2 slots.

1. I don't think anything is bottlenecking

2. Nope, you won't see any issues.

3. I think you can run 3 way.

Btw, do you need a good place for those 2 gtx 460's? (I'm still rocking my FX5200 AGP card

)

Why are you going for the 4gb versions? how many screens you rocking?

Would it not be more beneficial to save the extra money and go for a 3rd card instead of the 4gb ones?
