or this one:
Newegg.com - Computer Parts, PC Components, Laptop Computers, Digital Cameras and more!
Slightly better mobo manufacter (gigabyte) and much better chipset (785g).
785g has 4 things over 780:
-Completely hardware decode all HD videos (i think flash as well, check to make sure)
-HDMI output (very handy if you want to turn this combo in htpc because has the right parts)
-Slightly faster igpu (3200 vs 4200) with bumped core hz.
-Lastly most, if not all 785g has 710 south bridge that has ACC. ACC is a great bump to overclocking, but most importantly UNLOCKING cores, caches and multipliers.
785g chipset review:

Example of Unlocks:
1)AMD II X2 420 -> Opteron (18x multipler to 21x; free 600mhz bump)
2)AMD Phenom II X2 550 -> AMD Phenom II X4 (dual core to quad core)
3)AMD II X4 -> AMD Phenom II X4 (unlock 6mb L3 cache)
4)AMD II X3 -> AMD II X4 (tri core to quad core) or VERY lucky -> AMD Phenom II X4(tri core to quadcore with L3 Cache)
Of course, unlocking is like overclocking; depends on luck. But a lot of people have great success (over 50%) unlocking the extra cores and around 10-15% unlocking the extra core with L3 Cache.
I will post some results when I get a chance of my luck. Currently friend has AMD II X3 with MSI 785g board and waiting for me to help him build it.
Anyway, good luck B.
