i wasnt comparing the windsor to a phenom II because i skipped the 2 cores between the 5200+ and the 720BE i own.
i was comparing the windsor to the brisbane and the agena cores that were between these two
this is purely the fact why I used a Windsor dual core while Brisbanes and Agena's came and went. And it did well, it went to 3.2Ghz from mid 2's and was fast for its time how ever after changing to the tri core i have now i only gained 300Mhz and the time has come that you can get more cores and a faster processor now.
it just seemed to level off there for a while, clock speed and OC ability plateaued so more and more cores were added, now that the cores are being added stock and OC speeds are going up again and i am getting left in the dust.
Whilst I can see why brisbane 65nm and Agena = 65nm phenomenal disappointment were avoided when you had a good old windsor,
You havent told us where you feel your system struggles, you just state you will be upgrading your gcard eventually and in comparsion to your previous cpu you've only gained 300mhz. Like I said if its just in gaming then if your x3 can hold 3.7ghz with a little overclock on the nb-cpu, then that should hold out until either amd release something better than dozer or you could divert to intel.
