Need AM3 Sli Motherboard

[berkeleyboi]

Hi all, so I have every single part bought except for the motherboard. This is what I got right now:

CASE ANTEC|THREE HUNDRED BK RT - $33.66
DVD BURNER LITE-ON | IHAS424-98 R
PSU OCZ|OCZ600MXSP 600W RT - $55.75
Seagate 1TB Serial ATA HD 7200/32MB/SATA-3G - $36.55
Microsoft ANB-00001 Wired Keyboard 600 - USB, Black (M17-0025) - $13.99
Altec Lansing BXR1220 Computer Speaker System - USB Powered for Desktop and Notebooks (A162-0001) - $14.99
AMD Athlon II X3 440 Triple Core Processor ADX440WFGIBOX - 3.00GHz, Socket AM3, 1.5MB Cache, Retail w/ Fan (A79-0440) - $62.51
MEM 2Gx2|CORSAIR CMX4GX3M2A1600C9 R - $85.61
BFG GTS 250 x2 Video Cards - $113.19
Cremique Thermal Paste - $2.73

Total: $419.27

I'm looking for a good motherboard that can utilize my sli GTS 250s with the AM3 Athlon II 440. Don't want to spend too much but since I've already gotten some pretty good deals, I don't mind spending a bit more for a high quality motherboard. Speaking of which, how does this one look?

MSI NF750-G55 Motherboard - nForce 750a SLI, ATX, Socket AM3, DDR3, Dual Channel, PCIe, HDMI

Thanks in advance!

Well I was reading about 16x/16x versus 8x/8x and it seems like the difference in performance isn't as big as the difference in price. Is getting 16x/16x worth an extra 40 bucks?
