Op was talking about the MSI 970 mobo, not gpu.
If you are going to shop eBay, you need to be quite selective and savvy. I picked up a i7 3770k for $50 (usually $150ish), a fractal design r5 window for $20, 16Gb Patriot 1866 for $20, 128Gb Samsung 840 Pro for $20 and a nzxt Kraken x61 for $60. What I didn't do was shop mainstream. If you search for i7 you get thousands of hits, same with 3770k. The person who listed my cpu didn't list it as an i7-3770k but as an intel 3700k, so it didn't show up under the mainstream searches. The r5 was a scratch-n-dent, had a small crease in 1 panel, no biggie to fix, but was listed as (new-other) not new or used and as a fractal case with dent. Try not to buy from computer or electronic stores, they generally have a clue what merchandise they are selling and it's approximate worth, instead look for best offers from the little mom and pop eBay stores who sell baby clothes etc. They are usually more interested in turnover for mass profit, not individual profits, so you can low-ball offers. A grandma selling baby clothes usually couldn't tell the difference in an i5-3570K and an i7-3770k, they are just computer parts.
