clutchc :
If you have a high quality PSU of at least 500W and if you game at 1080p and if like to use the highest in-game settings you can, the R9-270X is definitely the way to go. The GTX 750 Ti is no slouch, (especially the factory OC models) but at 1080p it sometimes needs reduced settings to maintain smooth frame rates with low frame times. The 270X will give you lots more headroom there. But there are a couple cards that fall in between those two also; R7-265, R9-270
Thanks clutchc! Really does help, appreciate it!
Oh yeah and also, my friend would like a pretty good graphics card too, but his circumstances are a bit different, the budget he has is £150 or under. Thanks again!
