How important is CPU cash these days? (for gaming)

post #1 of 8
Thread Starter 
Hi all. I'm still looking to upgrade to a quad core processor. However, I'm torn between the q9400, and the q9450. That is what I can afford to do and that's it. The q9400 only has 6mb of L2 cache but the q9450 has 12mb of L2 cache. Do the games coming out these days make use of all that cache? Or could I go the cheaper route with the q9400 and be just fine? The whole reason I'm getting a quad core is to stop all these slow downs that I'm having, and so that I can run these more CPU intensive games they're putting out these days, like Crysis 3.

CPU cache is very important for gaming, so q9450>q9400.

Not sure how a Yorkie will perform in Crysis 3, but I am guessing that you really need to stretch that OC. 4.2 GHz would be ideal however I am not sure q9450 can do that.

That said, you also need a powerful GPU (GTX680, GTX780), and P45 or X48 motherboard with DDR3.

If I were you I'd buy a Q9650 and OC to 4.2 GHz with just 1.36V tbh. I am not sure the 9450 can make 4.2 GHz, and you WILL need 4.2 GHz if you want to play Crysis 3.

Last time I checked Q9650 went for, uh, abt 150 Euro at e-bay.de. It's really worth the extra cash, so my advice is to go for it.

Well maybe I should be asking a different question then. It seems like the more I ask around, the more I get the same answer. That I should just save up and upgrade to the I7 or I5 processors. But which one is actually more powerful? The latest 22 nanometer I5 chips, or the latest 22 nanometer I7 chips? I have not kept up with this stuff since about 2008.

The i7 will be more powerful -- called Haswell, for the latest 22nm -- than the i5. If you have the budget go for it... if you don't, though, an i5 is plenty for gaming. You'll need a -K suffix (e.g. 4570K) if you want to overclock a great deal, as they have an unlocked multiplier.

Edit: The difference is Hyper-threading, i.e. extra threads.

Went and looked around at newegg. The Haswells seem a little high, and I can't tell the difference between them and and Ivy Bridge I5's. They're both 22 nanometer, both have 6Mb L3 cache...and a lot of the reviewers say don't upgrade to Haswell from Ivy Bridge cause the gains are minimal at best. So which Ivy bridge should I get? And which z77 motherboard is known for overclocking well right now?

i5 3570k is the perfect cpu for games and other task that arn't able to take advantage of the HT on the i7.

Since you refer to newegg I'm assuming you're likely to live in either the US or Canada but in which state? Check if you have a nearby microcenter or if you're close enough to make a trip as the savings on the processors is hard to ignore.

Most reviews you read will say the same about upgrading from an ivy bridge to a haswell but either will grant you a world of difference for gaming, assuming you have the GPU to match. Since most of the price tiers on processors correlate with the previous generation give or take $10~ it's highly beneficial to go with haswell to get your moneys worth in the long run. Haswell not only provides up to 10% performance but offers increased sata 3.0 ports and USB ports as well as more flexible frequency overclock. If you're looking for the best value I would say asrock extreme4 series is generally a good recommendation as it yields as much as it's predecessor, z77 extreme4, and then some;overclockability and sli for the price.

Honestly its probably best to invest in a new system with newish architecture sandy bridge and up.
