Thank you all for the information on thermal paste. I think I have a good knowledge of it now. As for my video card, its an ASUS so I think it will do. But I dont remember the model and my son threw away all the documantation/packaging. I bought it about 2 months ago for my prebuilt that started freezing and crashing before I got it put in there. I do know that it is supported by WoW which is what it was purchased for in the first place. My only concern for it is that the PSU will be high enough at 450w to handle it. Anyone know where I could look to find out what model I have? Thanks.
