Well your comparing two completely different price ranges. The 650 is $80+ more than the 550.... However, although the 650 does perform very well. The better way to go in my opinion is going with the 550 or the 555 and attempting the unlock of the extra cores, it'll help greatly during multi-tasking not to mention future-proof as games are starting to get more complex and running more cores (sort of). However if your not planning to risk it and money doesn't matter, don't go for the 650 at all, add 20 more dollars and get the i5 750 or the i5 760. Much better deal.
well i have bought the phenom II X2 550 but i was asking this cuz i thot taht the shop owner tricked me into buying this processor, cuz i have always been a intel user and never ever thot abt amd.........
Doesn't look like your mobo can, but still try anyway. Try to update the BIOS first then enable ACC in BIOS to unlock. That guide i posted will also help or WR2's. About the 550 it's unlockable cores make it a great buy, remember though it isn't 100% it will unlock. I bought one and mines didn't but doesn't mean yours can't. The unlocked core will still allow a pretty decent OC to around (the sweet spot) 3.6-3.7ghz. So you'll gain a significant improvement even w/o OC and just the unlock.
normaly u get the more bang for the buck with AMD, but the i3 i5 i7 gets you hyperthreading which give you 2 or 4 more virtual cores, there not as powerful as true "real" core are but can help handle workloads better. i prefer AMD tho
unlocking doesn't void warranty, it's just it's not guarenteed to unlock. But it doesn't void, thats the great part.
thanks a lot guys for ur helpfull replys and answers
