Hi, I'm a medium to low hardware technical knowledge guy here,
I'm thinking of building a new rig and obviously the $200 price tag of the i5-750 is attractive. If I do get this processor, I would want to OC it a bit, but apparently Lynnfield has trouble overclocking much with the stock heatsink.
I tried looking up some reviews for some HSFs, but since it's so new it's hard to find any review for 1156 compatible HSFs. Anyone know a good heatsink?
Secondly, I see some heatsinks selling anywhere from $20 to $80+, if I am paying that price for a nice fan, wouldn't it be better just to buy the i7-860 then, it's only $90 more.
Oh ok. Well to be honest, I am thinking of splurging with crossfire'd 4870's. Wonder if the 750 will be the bottleneck? I have it all laid out in my newegg cart, lol, but since I'm a hardware noob, not sure if its a good balance.
Lower than "expected" fps from xfire or sli is possible because of throttling data from the vid cards, but not because of cpu processing power.
Dunno what resolution you are running, but at 1920 one 4870 should be enough, and the 5xxx gen coming out next month should have single cards 2x as fast. No worry about 750 throttling that single card.
16 paths to move the data from *one* card to where it has to go, so a higher data rate (more pixels if you will) is available to support a higher frame rate.
(When these cpus are driving xfire/sli, there would be two cards, each only having 8 lanes, or half the data rate a single card would get. If the cards are fast enough, the data rate starts to limit you instead of your graphics cards.)
Okay... well I've decided to use the i5-750, since it's the same as the 860 w/o hyperthreading (which doesn't matter in games for now). My monitor will be 1920x1080 or something. As for the video card I will wait until the 5850 comes out, and get a single. Also for the fan, I am getting the 1156 compatible coolermaster at newegg for $29.99
