> Dabar del proso - jei vistik imciau mamke su Z68, tai tu prosu i5 yra bent keletas pasirinkimu - ten labai 
> svarbu tie keli simtai MhZ nes tai kelis simtus gali kainuoti, t.y. 2.9 - 3.3 GhZ

O nebus prabanga "is esmes ofisiniams" poreikiams?.. 
Z68 - mokama uz tai, kad dera i5-2600K, turi video, SSD Caching..

* Core i5-2300, Core i5-2310, Core i5-2320, Core i5-2405S and Core i5-2500K does not support Intel TXT and Intel VT-d.
* K processors are unlockable and designed for overclocking.
* S/T processors feature lower-than-normal/an-even-lower TDP 

Siulyciau neziuret i i5-23xx, nes uz +23 Lt gausi ne tik tuos TXT, VT-d (gal ir neprireiks), 
bet ir 0.1GHz + gal kada parduodant sugrotu ir tie TXT, VT-d .. 

Orientuojantis i 579 Lt, galima pagalvot ir apie i5-2400S (+9 Lt .. mazesnis TDP faina, 
o Turbo pas S-us "stipresnis".. Tik tas Turbo nera QUAD'e 3.3GHz .. 2400S'as Quad'e bus 2.6GHz)
1/5/9/10 << aktyvus 4Core / 3Core / 2Core / 1Core ... tas Turbo man beveik neskamba.. 
nes realiai, tai i5 dirbdamas dual-core.. gali pasparteti ~0.2-0.3GHz.. gerai, kad gali, bet didelio ispudzio nepalieka)..

Nuo 579 Lt iki to, kuri galesi pasispartinti (ir pateisinti Z68 privalumus) truksta +85 Lt
Uz tuos +85 Lt gauni dar ir stock +0.2GHz .. Taip pat "K" turi geresne isliekamaja verte..

Jei "galingas ir dabar" - bus paprasciau, jei nusiteiktum CPU+MB = ~340 + ~660 = ~1000 Lt .. ir +RAM,HDD,SATA_DVD(?)
Jei atrodo daugoka - nespjauk i ta G530 su H61 .. nera jis toks silpnas (aisku, atsizvelgiant, kad 3X pigesnis MB+CPU)..
