Usually, game performance is independent of drive speed, but loading times are affected by it.
I usually only recommend lower end ssds to gamers primarily for that reason, but you seem to REALLY like speed, so I'll recommend a higher endmainstream ssd. Of course, the highest end ssds are still reserved for other kinds of users.
I recommend either the Toshiba Q series pro or ocz vertex 460. They are very very fast drives that have a good price as well.
I do not recommend the Samsung due to inherent issues with a technology called TLC. I do not recommend the ADATA because the drives I did recommend are much better.
So look for those two drivers at all the physical and online computer stores you have access to and buy the one you can get for less.
