    i5 4670
    H97 or Z97 motherboard.

    GTX 750ti: http://uk.pcpartpicker.com/parts/video-card/#c=164&sort=a7
    OR
    R9 270X: http://uk.pcpartpicker.com/parts/video-card/#c=147&sort=a7

    (270X is much faster, but will likely be held back a lot more by your current CPU)

    Would I be able to take a gtx 660?

    Yes. It performs between the GTX 750ti- R9 270X, but closer to the GTX 750ti.
  4. Also I am curious about if I upgrade my cpu to an i5 750 or an i7 870/920 what gpu then?
  5. I wouldn't get the i5 750 because it will perform like a 3rd or 4th gen i3. The 920 is still being used by quite a few people with newer video cards like the gtx 760 and 770. The 920 is a pretty good deal if you can find one on ebay for 50 bucks, or even a 950 sometimes will go for about 60 to 70 bucks. If your power supply can handle it I would get the 920 and the 760. That would be the cheapest way to get better performance, but if you plan on having that ability to upgrade the future, something like the xeon and the asrock z97 pro 3 would be a really good choice.

    They would be a better match with the R9 270X than the i3. And with one of those CPU's, the best i'd go for would be the R9 280X or GTX 770 & that would see out the system's life. However....

    .... investing in old technology isn't always the best deal. When components become rare the price can remain the same as when they were new, or indeed, the same price a much improved newer i5 processor.

    Unless you can get one for cheap & really cheap, it maybe worthwhile. But when your spending as much as a modern CPU would cost, it's not worth it. As you may as well buy a new value motheboard & a modern quad core CPU.
  7. you could get a sapphire 270 dual X at £126 which is pretty fantastic.
  8. Upgrading to a i5 750 or ... would be pointless imo.
    Even now dualcores are enough to play games and seeing that yours is overclockt and has hyper threading is it my opinion that you just should get the best gpu you can get for the money and see how it does.
    That r9 270X does look good imo and could be taken to a newer build when/if you get one.
