I've been looking to upgrade my video card and was wondering if i should get an nvidia gtx 260 or the ati radeon hd 5770 about $30. Anyone know which one will perform better and a suggested psu would be great also. I have an eMachine et1330g-03w would these graphic cards work with my computer?
If that's the model I found (their site said that model doesn't exist, so I found the one most similar in name), NEITHER card will work in that system, as it has only a 250w power supply.
You have VERY limited upgrade options without replacing that power supply, and even then, you will be very CPU limited (it has an older Athlon dual core), I think that even getting a 4650 would be pushing it on that power supply.
a 4870 is probably the best upgrade due to being cheaper than both of them and equal to the 260 in terms of performance, and better than the 5770. dont get the 5770 for dx11, as it is not powerful enough to make the most of it, and the power savings arent noticeable on your electricity bill.
