Perhaps only a handful of games can utilize 6 CPU cores.Of those I only know 1 so far that can utilize hyperthreading (FSX) although perhaps a few other recent titles could as well.When one compares Core i7 980x vs Thuban 1090T in gaming obviously the Core i7 would win easily hands down compared to the Thuban.However in terms of price per performance the Thuban would win for the very few games that support 6 cores.The i7 980X CPU is outrageously costly.
In a way the 980X is not worthwhile for it's extravagant high cost.
A much better gaming CPU would be the much lower priced i7-2600K vs the i7-980X even with its 6 cores.Yet in comparison the i7-2600K is Intel's new line so comparing it with a old Phenom X6 line is not fair either.It would be better to compare it to AMD's upcoming Bulldozer line and as of yet we have no gaming benchmarks.
So far the only reasonable high performance gaming CPU would be the i7-2600K
over the too costly i7-980X and over the under performing older Phenom II X6.
Even the lesser 4 core with hyperthreading Core i7 -950's easily outperform the Phenom II X6 in gaming with even the few 6 core optimized games.
Bulldozer should come very close to the i7-2600k though and even the i7-980X.
Still there is several months wait on that.The i7-2600K's should have their corrected motherboards before that time so my vote would be not to consider either the ridiculous costly i7-980X or the Phenom II X6 for gaming
I do agree with you that Intel is better than the other one,but it costs much,I am planning on buying a CPU which can perform many current games and next 2 years and does cost me that much as i7 980x,I dont know how much i7-2600k costs,but I am sure it is expensive as well,my saved-up money for CPU is 260$ at the end,no more no less,,,,I am stuck,,and this Thuban is very tempting,,,,,thanks a million for your advice.
