I'm looking to upgrade from my Intel core 2 extreme qx6700 2.66ghz to a core i5 2300 2.8ghz, but I'm not sure if it is a big upgrade or not, I have had this processor for a while so it seems logical but I'm having trouble comparing the two with each other to find the major differences.
I'm planning on building a new PC, minus a power supply and Graphics card as the ones I have are fairly new and still good. I'll be using the PC for gaming mostly, any help would be appreciated thanks.
Not that i can add much, but i can say there should be a difference. I mean honestly i would think there would be, its a complete different architecture. I'm in a similar boat, i have the Intel Core 2 extreme qx6850 OC'd at 3.5ghz. But i plan to just go straight to the 3930k which i feel confident is a big bump over say if i got the 2500k, i believe that in order for me to upgrade i gotta have more then 4 cores. Eventually games will utilize the extra cores and threads. If i were you, and price is an issue why not just get the 2500k. It does everything, and you can overclock if it be that day you want get extra frames out of it, it will OC no problem. Just my opinion though.
i recently just replaced a Core2Duo e6850 (a lesser chip then what you have, but not by a lot) with an i5-2500k(no o.c'd yet) and it's like night and day, i gained ~15 FPS in BF3 with the same old 5770 I've had for the past 2 years, same settings/resolution just a new cpu/ram/mobo
Well, for what it's worth, I think you should save your ducats and get the 2500k, it is worth the extra 50 bucks over the 2300. Yes, the 2300 stock is a big upgrade for you (I went from a Q6600 2.4 Ghz to an i7-860 2.8 ghz and it was a HUGE improvement), but that same upgrade can be experienced 2 fold by getting the 2500k and overclocking it to 4.0 ghzish. Not to do that is wasteful.
