So I bought a used XFX R9 290X from a microcenter about 3 months ago along with my entire build(everything else new). after Fallout 4 came out, I bought it and started playing it (high settings mostly) and my screen would randomly say lost signal, but my computer would still be on and everything would be back to normal after I restarted the computer. To put it short, my screen kept doing this, I removed the GPU and it stopped happening. I requested an RMA (which took 6 days) and sent it back 3 days before thanksgiving. It really made me mad I could not play fallout over thanksgiving weekend, so I am wondering if anyone here has experienced this with XFX products and/or has done an RMA with them. Was the RMA successful, or did they send you another busted card? Maybe it was my fault for buying a used GPU, but the card looked like it was barely used at all and it was on sale.
