connection problems have no relation with your PC whatsoever. Whether you're on a 12 years old PC or a brand new one, your connection will stay the same. Perhaps you should up the connection speed to 2mb or 4m.
As for the motherboard, find the one sold by amazon themselves, it should cost $120.99
If you want my opinion, get a GTX 670 instead of either of the two GPUs. The reason I went with 7950 instead of 670 is because it was $100+ cheaper. The performance difference isn't big so that shouldn't be a big of a problem to you. Don't look too much into benchmarks as you'll get yourself confused. Many of them are biased and would compare on different basis.

It's higher than the other card's price range but it's worth getting on the long run, and Gigabyte's GPU are pretty good and durable.
