i7-930 vs i5-2500k ($99) vs i5-3570k($169)

post #1 of 33
Thread Starter 
So I have an i7-930 @ 3.8 but am currently being tempted by these two stellar offers…I love microcenter. I’m wondering which offer people think is better and whether either would provide a significant improvement over my 930. Current machine specs are in my sig. To summarize, I’m running a reference EVGA 680 and game at 2560x1600 or 4960x1600 PLP when possible/supported. I have another 680 on the way but will likely sell it before even opening it for a 4gb version or GK114…eventually. Appreciate input...ty.

I5-2500K = $99.99

i5 3570K = $169.99

Will you purchase a new 1155 motherboard as well? If so, I would pick up the 3570k because Microcenter has $40 combo discount when you buy a 3570k and any compatible motherboard.

Not entirely necessary, but you will see increases in games that scale with CPU power, and the Sandy/Ivy chips will overclock considerably higher too.

Oh and you really should be aiming for 7970's at those kind of ultra high resolutions, if you are buying from this generation. But really just hold onto your current 680 until the generation of GPU's are out.

And due to that intended upgrade path, you should get the i5 3570k as you will want PCIe3 in future, probably before you will want to upgrade your CPU and platform. The Sandy is better value, undoubtedly, so if money is skint then get that. But if you can afford it, get the 3570k and a nice motherboard. And some of those Samsung Green 30nm ram chips and overclock the bejesus out of those too. Ivy bridge can get some pretty high memory clocks.

But honestly, objectively, and over-all, I think you should save your $$'s and wait for Haswell and whatever the next GPU's are. Double down on a full overhaul in 6-9 months or so and your current rig will hold up till then perfectly and still retain a resale at that point.

No reason not to get a i5 for $99. thumb.gif

Chances are the 2500k where ever you are located has sold out. I'd go with the 3570k and pick up a Asrock z77 extreme4. $265 + tax is pretty nice. Even if the 2500k isn't sold out I'd probably still side with the 3570k combo since a comparable motherboard without the combo would put the price within <$40 of eachother.

If your store does by some chance have 2500ks left in stock and you choose to go with the 3570k combo you should pick up the 2500k and try offloading it to someone on OCN for breakeven. You'd certainly make someones day I'm sure. tongue.gif

Hell for 99 bucks, you might as well build yourself a second rig.

Thank you all for your feedback.

foxrena: I will have to pick up a motherboard as well so the IB/MB suggestion sounds logical…ty
willibj: Regarding the 7970, I’ve had multiple and prefer the 680…just runs smoother…imo. The 2gb VRAM and memory bandwidth are issues though. I’ve been holding off on the cpu/mb side as the performance gains seem pretty marginal relative to my current setup. I think your ultimate suggestion to hold off for Haswell is a good one…and what I’ve been thinking.
paulerxx/Ryleh: Ya, pretty hard to turn down a i5-2500k for $99. The MC near me still has two in-stock so I will probably still pick one up, if only to sell it. I appreciate the 3570k/z77 extreme4 combo deal suggestion... a better long-term approach.

That's kinda what I was think...I have all the necessary parts to build another machine...except the motherboard.

2500K imo
post #10 of 33
All the i5 2500K's I had could overclock to 5.0GHz within safe voltages and temps. The 3570K's I had could only overclock to 4.6GHz within safe voltages and temps (4.8GHz if outside safe voltages and close to unsafe temps). Basically, the 3570K 200MHz slower than the 2500K are about the same in benchmarks scoring.
