Default Gtx260's sli setup?

I'm planning to get a new rig with a gtx260, 4gb DDRII, q9300; and am deciding to put it on either an MSI p7n platinum or ASUS p5n-d.

I realise that these two have been matched up on many sites on
many occasions but I have decided on the p7n platinum on one condition:

***I plan to get another gtx 260 in a few months time, will the mobo's ability to only run at PCI 2.0 x8 for each card (as opposed to both at x16) be an issue?***

I only intend to OC the CPU to c.3.0Ghz so am not worried by the (probably fair) claims of the boards being poor OC'ers.

***One last thing, I intend to put this in Antec 300 with a coolermaster 700w PSU. Can I assume this would be enough power for 2x gtx260's?***

Cheers

Personally, I don't think that PSU will be enough, esp if you are overclocking...

Sorry Vanzagar, should have checked that site properly before. A bit slack. Much obliged for pointing it out.

I'd better bump it up safely over 800w.

**Anyone got any ideas whether this lack of two full pci x16's running at fulll speed, will slow down a pair of gtx 260s?**

I can't find anywhere that says that a x8 speed slot would be too slow, but it sounds unusual for a fairly new GPU model
I don't want to create a bottleneck for GPU's on a brand new setup.

On the other hand if you reckon this us just noob thinking... let me know!!

My power supply seems to handle everything just fine.

That's really good to know... I just got a 1000W Corsair for my two gtx260's, looks like I have a compfortable cushion... are your gtx's and cpu over clocked? how many hard drives you running?

Vanz
2 HDDs
CPU @ 3.2GHz

No need so far to overclock the cards.

If your motherboard has PCI 2.0 then running at 8x instead of 16x you want notice much difference, in some games none and others maybe 1 FPS or 2 FPS at least the review sites I have seen.
