HD6850 (i3-2100 vs i5-2400)

Right now, I have an i3-2100 and a sapphire HD 6850...I notice sometimes (just cause 2) my GPU runs at 100 percent while CPU is lower. Other times, the GPU does not run at 100% very often (yet framerate is not say maxed at 60) while the CPU appears to be the bottleneck...

My point is, if i went up to the i5-2400 how would my FPS increase in CPU hungry games? The i3-2100 does well usually, but would going to the i5 not help because my graphics card isnt powerful enough to match it anyway? Does the i3-2100 perfectly compliment my hd6850? I have trouble telling.

More about : hd6850 2100 2400

You'll will see noticeable gain with i5 2400.If you want to upgrade get a i5 2500k..

ya get the i5 2500k bcz it is overclockable if u want..it is the best i5 processor and i think this is the best cpu for the gaming with any gpu

I have an i3-2100 and a mid-ranged GPU, as well as a motherboard that wont CPU overclock.....so I dont know why you automatically change the subject to the 2500k ...hmm?

i don't know what game(s) your running but i can tell you my i3 2120 does fine with my 550ti. (a little weaker than your card though)

i just ran some benches in COD MW3 for my little experiment of undervolting my cpu for better/lower power consumption because, well thats all i can do for geek fun with it.

bottom line is at no time did i get the "feeling" my cpu was causing a problem. actually the highest load on my gpu was 67% and cpu was 25ish%. and the times my cpu had a load is when the game/map was loading.

i am starting to think a sli or Xfire configuration is what would cause a bottleneck.
but would an i5 improve game play? i would think so.

Seems like you should do your testing with something more demanding if your GPU and CPU are barely stressed?

The i3-2100 should be fine for the HD 6850. Most games only use 2 cores, however there are a few games that do benefit from 4 cores. If you know you are going to be buying a game that can use 4 cores then you may want to opt for the i5-2400.

You could also opt for the slightly faster i3-2120 CPU instead if you want to keep costs down. Newegg is currently selling the i3-2120 for $128, plus if you enter the promo code EMCNGND32 that reduces the price by $15 down to $113, but it expires on March 12th.

The one thing that a core i5 has that the core i3 doesn't have (other than 2 extra cores) is Turbo Boost which is an automatic overclock as long as temps are not very high.

The extra 200MHz of the i3-2120 compared to the i3-2100 should help make up for the lack of Turbo Boost and lower price should help sweeten the deal.

your absolutely correct. BFBC2 did just that ;) 
http://www.tomshardware.com/forum/327800-28-undervoltin...

99% on the gpu and no more than 50% on the cpu except when the game was loading.

i need a bigger card. :( 

and to the OP.

no matter what anyone else chooses to believe, if your gpu is running 100% and your cpu isn't sweating, you need to upgrade your GPU for a performance increase worth spending money on; upgrading the cpu would NOT be cost effective.

yeah i changed my mind since last post but not really.
