Throwing away my phenom2x6 1055t, and getting a i2500k and my current build has 2 6850 crossfired, should I get a new PSU? I have 2hdd, and 2dvd writters...thxs.
Here is also an easy answer, see if it works. If it is not enough for whatever reason, then consider ordering a new PSU.
If your PSU is this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817207002 You should be good to go.
Yes, that is the one I have, questions...will I see a big performance in games and video editing with this new setup?
From the benches that I have seen and from my own personal experience going from a Core 2 E8400 to my current specs the difference was night and day. With your use of a X-fire setup I think the gains will be even more pronounced. Keep up posted though, and good luck! P.S. Just noticed you asked about video editing. Going from the X6 to only a 2500K you should stay about even there. If you are really concerned about a notable difference in video editing I would suggest the 2600K. HT helps immensely in threaded video applications. Games not as much.
