thats a good point
btw, 955 is 13.5k locally, ut the 500 bucks wont make much difference.
But Intel is changing platforms and sockets every now and then. And with past experience, even if sockets are same, newer proccys wont fit in older mobos.
for eg, LGA 775 was here from 915, 925, 945,965, G31.....X45 mobos. But newer proccys wont fit in 915/925 mobos even though the 925 was their high end mobos once.
Even their newer upcoming corei5 is gonna use newer socket. While the i5 become mainstream, i7 will remain as premium and i7 920, and 940 will be discontinued, and only i7 955/65 will remain and will cost almost triple[~750$] of current i7 920.
SO to juice the i7 965, they gonna get some new chipset or innovation and current most expensive X58 mobos like EVGA classified will become kinda obselete when u plan to upgrade later from i7 920.
But in case of AMD, upgradibility is main feature. u can use a PII in even older AM2 mobos like M2NE[nforce5 Ultra] or a 690G mobo, to 780, 790 mobos.
And AMD promises all upcoming proccys to be fully compatible with current mobos. So an AM3 mobo will take atleast 3 or more yrs to be called obselete[when 32nm bulldozer X8 or X12 gets released on Q4 2010]
And MSI 790GX-G65 is Am3 with DDR3 support, and comes for 8.5k
For gaming, surelly a GTX 260 will hold u back on a full HD 1080p display. It wiser to invest the extra savings[8k+] for the GPU and get a GTX 275[18k] or 4770x3 CFX[better][19.5k].
And for gaming purpose, even a non OCed 955 matches to a non OCed 920 and only if the GPU isnt bottlenecked. Ull need a hefty graphics card array[SLi or CFX] to bottleneck either a pII 955 or i7 920.
