My CPU and GPU

Hi, I'm a little upset after getting wrong information from the Tom's Hardware community...

I had asked a question about I built I was going to put together, I had chose an intel i5 2500k and a Radeon HD 7870.

So I had 'experts' say they looked and those work great together... order the parts, read the manual... and the i5 2500k DOES NOT support the 7870. It works... but I'm 15-20 FPS behind because the i5 2500k doesn't support PCI 3.0.

So could somebody who knows about processors please let me know of an actual processor that would be good for my 7870?

I guess I'll have to put my i5 2500k towards a work horse or something...

Thanks.

gr8, why don't u file a law suit against THW?!! ;)  man, there's no such thing as "the i5 2500k DOES NOT support the 7870" !!!

The PCIe 3.0 thingy is useless as of now.....check this out regarding a more powerfull HD 7970....

does your motherboard support pci-e 3.0?

if not wont matter if you put an ivy bridge cpu in

and as pointed out dont think cards will run faster on pci-e 3.0 anyway

and if we are so useless here why come back and complain then ask another question?

you have the whole web to get your information from nobody forced you to take the opinion you were

given

since there is No measurable FPS difference between PCI 2.0 and 3.0

the problem lies else where . . . .

Don't think there's any way a 2500K on a Z68 or Z77 is throttling a 7870. *That's* the bad info you got somewhere else.

to the op right now pci 2.0 or pci 3.0 for a video card means very little today. most new video cards cant max out the pci 2.0 bus yet at 16x speed. same goes for most ssd and sata 6g ports. next year card may start pushing the 2.0 bus speed limit but the newer ones cant. I would start out with the simple checks first and go from there. check that your mb has all the bios updates and that your ram it runing in the xmp profile. most mb the ram going to default to 1333 if it 1600 or faster. check that you have the newest chipset drivers and amd drivers and ones for sound and network... make sure your anti virus has a gaming mode for full screen. make sure you have all the direct-x loaded and updated. make sure the patches for the games are installed and if need be game line tweaked. also look at toms hardware review...they dont connect a high end game card to an i5. most i5 going to have a 7770 or a 560ti or 560ti installed. tom uses an i7 as there test bench cpu. that due to it having a larger cache and hyper-threading..if it under 30 days i would call the place you order your gear from and do an rma. you eat 10-20 dollars for restocking fee. it be a lot less then eating a cpu. i look into a mb that does 16 by 2x or more for two-4 cards. most low end mb now and you got read the small print so 16x by 1 and 4x on the other video card slot. mb like sabertooth z77 is 8x if two cards are used. it run in both pci 3x or pci 2x mode depending on the cpu.

there is no such thing of a 2500k not supporting a 7870, there are plenty of rigs on here that with the setup. secondly pcie 2.0 and3.0 does not make any difference if your running at 16x even at 8x. lastly we can not really troubleshoot the problem unless you give us your systems whole specs.

P.S. please don't say its the THC fault for this, if this is the only source your using then its your fault.

If your losing significant FPS you are probably one of those clowns that somehow managed to have the card running at x4

*edit to add* heres a great replacement for your 2500k.... bargain too
