Hi guys,

Looking to add a 2nd 7950 3GB to the PC which I built a few years back as it's starting to struggle now on newer titles such as Project Cars and GTA V at higher settings however I'm not sure if my PSU is completely up to the job. It's an 'Antec True Power 650w' which I bought from OcUK in 2011.

Rest of the specs are:
Asus P8P67 LE
i5 2500k
8GB
2xSSD's
1x HDD

What do we reckon, is the PSU up to the job?

Thanks :)
 
Wouldn't bother, sell your current 7950 and pick up a good deal on a 290X for more consistent performance, and not having to rely on crossfire profiles that come really slowly today if ever..

That's another thing I was looking at, might just do this :)

Edit: On doing further research I've followed your advice and just picked up a Corsair watercooled 290x instead :D

If it's for Project Cars you really want to go nVidia. You might not like it but the 290X is about as fast as a 6600ti in Project Cars.
 
I'm sure some drivers for AMD cards will be released soon so not a problem for PCARS or the Witcher3.

A 290X runs at about the same speed as the gtx 970 on W3 with no Hairworks. Hairworks tanks performance on Nvidia cards too so not many would be using it unless they have SLI.
