I understand that the Titan is the single GPU card to beat... but how does it compare to the 780? as it will be a similarly priced card...?
also... i know the R9 290x is the upgrade to the 7970, but what is the step down? which card is the upgrade to the 7950?
Its probably not going to beat the GTX Titan, but get fairly close, it should be around or just past the GTX 780 and be ~£50 cheaper.
The 7970 is the next one up from the 7950, but there isn't much in it, if you already have a 7950 i wouldn't bother, wait for the new GPU's, there might be an Hawaii GPU in-between the 7970 and R9 290X (R9 290?)
