Should i upgrade to intel?

i am planning to upgrade to an intel socket 1155 (i3/i5 2nd/3rd gen) from am3+ (FX-4100) which means changing the motherboard too and reloading windows but i wanted to know if it is worth the hassle/money because i currently have alot of programs/games installed on my hdd and i dont want to loose them (is there any way of backing them up?), i have heard intel are launching the new Socket 1150 (Haswell/Broadwell) in 2013 rumours say this June (1 months time) so i am not sure whether to upgrade to socket 1155 or wait for the new one , i am mainly changing from amd to intel because amd dont seem to do any good processors anymore the processors seem to be vanishing from shelves in stores intel is dominating the market with better processor architecture and the fx-4100 is a bit of a fail purely because software hasnt caught up on utilizing the so called "four cores" amd fx was meant to give , i thought it was a good processor when i bought it you know a four core high clock speed , high cache but intel i3 owns it , am3+ just seems to be dead i have to downgrade from my fx-4100 to an older processor (AMD Phenom II X4/X6) which is older but better i have heard but there is no sort of futureproof reliability/performance/stability or upgrade option its downgrading only (in terms of new architecture/Processors)

Correct me if i am wrong , this is what i have read online and been informed by pc technicians i am very dissapointed as i went AMD not just for cost reasons as i was willing to pay a bit extra for performance but i didnt think it will be this bad not only in terms of performance as i could have paid like £20 extra for an i3-2120 or something but in terms of upgradability.
