Hi there. I have exactly the same situation as OP so didnt want to open a new thread. Found crucial m500 deal for 107$. Samsung 840 evo 120gb is 100$. That samsung 840 evo is the lowest price I can get in my country where electronics tend to be pricey compared to other countries plus all consumer products have %18 tax.
Would it be worth going for samsung for extra bit of performance or go with crucial for extra space? I'm leaning towards crucial but still not sure if its worth dropping performance for extra space. If samsung can make a real difference in desktop usage, I will pick that. I'm mainly using my pc for browsing, watching videos and sometimes playing lightweight games generally being WoW or LoL.
