I'm looking in buying an Intel Pentium 4 3.80 GHz and got an E5300 2.6ghz would there be a big notice in game while playing? With my GPU i should be playing on high to ulta setting but i'm stuck at Low and 15 fps to 10 Gpu is MSI 7770 Ghz edition.
If you can find a better CPU for me go ahead if it's 30$ more thats my limit. Socket is LGA 775.
A P4 HT might run BF3(2 threads), but it is most definitely a downgrade from pentium e5300. Back when core 2 launched, the slowest sub 200 dollar e6300 at 1.86ghz was about as fast as the previous 1000 dollar pentium extreme edition 965 hyperthreaded dual core at 3.73ghz. The main things that made core 2 so much faster were 1. a shorter pipeline(less than half the stages of prescott/smithfield and cedar mill/pressler for better instruction efficiency), 2. wider core(4 way super scaler versus the previous 3 way setup), 3. more L1 cache(P4 L1 cache was lacking, but core 2 was about as much as intel has ever had in a chip), 4. Large shared L2 cache(versus smaller L2 cache per core) and 5. built with dual core in mind from the start(cores can talk directly to each other now without having to go out to the chipset and back like before). Yes, P4 had math units that operated at twice the clock speed of everything else on the chip(not sure if fp, int or both), but it seems core 2 far exceeded intel's expectations and doubled ipc(insructions per clock) performance versus the then outgoing P4. The P4 you speak of at 3.8(has to have HT at that speed) is about half the speed of a core 2 e4300 at 1.8ghz. Your e5300 is basically the same as a e4300, except it runs 800mhz faster(ie the better part of a ghz). It may well be a cpu bottleneck to your current graphics card, though. You might be able to find a faster dual core on ebay or something(like a e8400 or e8600), but a quad core would be better. However, it seems as though your mobo doesn't support quad core processors.
