This is going to be my 2nd card purchase like ever and I'm really interested in this particular one but I would like to get others' feedback regarding the Manufacturer of this card in general.
I had my 7950 die on me, RMA took 2 weeks or so (about what I would expect). All in all was pretty satisfied with their service. I believe they're run by Tul Technology Unlimited out of City of Industry, Cali.
Hmm...that's a pretty old card which, I'm guessing, your card has been out of warranty for a while. Have you considered playing around with it's cooling? Like, slapping a water cooler on it?
Right now I have a Asus HD 7970 DCUII that I tried to get a full replacement since the 1st RMA didn't fix the artifact-ing on it.

Reinstalling windows help with most of it but there's still some artifact-ing. I requested a cross-ship replacement over the phone and they politely refused to which I politely bit my tongue. Since it came back from Asus' RMA Dept. that card still artifacts in BF4 and Crysis 3, and, with the added annoying vibrations that wasn't present before sending for RMA. Honestly, the card still plays like a beast with no problems with my Steam games since I do make a lot of screenshots as you can apparently see from my steam profile, Odd that it only artifacts BF4 and Crysis 3, which is understandable since they're demanding. It's likely going into another build as a side project.
Hardware Canucks was able to achieve a core clock of 1219mhz so I guess it evens out the Lighting's 6.6mhz memory clock. The MSI Lighting seems to be the only model worth buying, their Twin Frozr counter part are notorious for the fans leaking, LOL. Plus, the warranty is better. Hmm...but significantly more expensive.
