X3 720 vs X4 640 vs X3 445? Tags: CPUs Last response: September 29, 2010 9:03 PM in CPUs Share squallypie September 29, 2010 6:09:10 PM X3 720 ( or 740 ) vs X4 640 vs X3 445? They are almost in the same price range. The X2 555 looks good too but its just two cores and i cant afford to take the risk of unlocking. I can afford to move upto the 955's price range, but am i going to see huge increase in performance? Uses :- Gaming. Most of them are GPU intensive but i have some games like FSX that are really badly CPU intensive. Resolution will be 1680 or 1920, im not sure yet about the graphics card though. Most probably a 5770 or a GTX 460 to begin with. and then SLI or CF later.. BTW, are nvidia chipsets for amd CPUs as good as amd chipsets? or is it better to sli with an intel cpu instead?

You can compare the different CPUs here: http://www.anandtech.com/bench/CPU/2 and see if the differences are worth it between the X4 645 and 955: http://www.anandtech.com/bench/Product/188?vs=88 As for chipsets, if you get the latest nVidia chipset you will be perfectly fine.
