Yes. All Core 2 processors are 64-bit.
it depends on your gpu,i run black ops on e2140 and in 9800gt 512mbddr3 and in high settings :D
No, you need a 2.6 ghz dual core, or a quad core to run it at its full potential.
Intel Pentium Dual-Cores are identical in architecture to Intel Core 2 Duos. The differences are:Intel Core 2 Duos have a larger amount of L2 cache. In certain applications, a larger L2 cache can provide a major boost in performance.Intel Pentium Dual-Cores lack some features that the Intel Core 2 Duo includes, such as support for Intel VT-x (used for virtualization) and TXT (Trusted Execution technology).As of September, 2009, the fastest FSB supported by the Pentium Dual-Core line is 1066 MT/s. The fastest Intel Core 2 Duos support an FSB of 1333 MT/s.
It doesn't particularly excel in any given benchmark, but it is by no means weak. It is faster than an Intel Core 2 Duo E4400, and only slightly slower than an Intel Core 2 Duo T7600 and about 9% slower than a E6600. That being said, at <$70 (6/09) it is an excellent bang for the buck CPU, in spite of it's Pentium name it's actually an Allentown Core 2 Duo based product with low wattage and overclocks very well for those so inclined scoring over a 5 on the Vista CPU test.
Pentium D is nothing but 2 Prescott Processors side by side…When it runs, it tends to get very hot, and is hence not a good OverClocker…Intel Core 2 Duo processors are next gen processors from Intel on 65 nm platform… developed from Ground Up with new architecture called Core… so they are whole new Processors.Expect one Core 2 Duo Lowest End Processors like E4400/E4300 taking up and beating Intel Pentium D 3.8 GHz ones with ease … runs damn cool and super over clocker…Intel Dual Core Processors are just launched striped down version of Core 2 Duos.. there are 2 in the market for Desktop range, E2140 runs at 1.6 GHz with 1 MB L2 and 800 MHz FSB and E2160 with 1.8 GHz with same specs of E2140…. these are not Pentium D rather they are same batch like Core 2 Duo based on the new Core Technology…. they perform same like Core 2 Duos but they were launched with a very low price to counter the market of super low cost but high performer AMD X2 range line up to AMD X2 4000….
