Need advice on new Intel rig.

post #1 of 5
Thread Starter 
My first post on the Intel side of the forum.
After some research I've decided to venture over to the Intel side of things and now I've come up with a few components for a new rig. The system would be used mainly for gaming (and FSX) and general everyday stuff.
Since I'm not familiar with Intel hardware I have a few questions.

My budget is £400 max . Can you please give me some advice on the parts that I'm currently considering ? I'm especially interested in what you guys think of the mobo. I've read mixed reviews about it but unfortunately my budget is tight... I'd love to get an ASUS board, I've never used anything else.

CPU: i5 3570k

Motherboard: AsRock Z77 Extreme4

RAM: Corsair CML8GX3M2A1600C9B LP Vengeance Memory 8GB 1600MHz CL9 DDR3 Two Module Kit

Cooling: Phanteks PH-TC14PE - planning to use with stock fans

Either this or an AMD based rig with FX8350 as the heart.

So, my first question would be the Cache. The 3570k has 6 MB Cache while the FX8350 has 8 MB cache. How much effect does cache have on performance in general ?
Second question would be the "instructions" that the chips have as a feature. The FX8350 has more instructions and features than the 3570k .
Another question, if the Intel chip enabled me to do so, could I get a stable 4.5 GHz oc with reasonable temps using the Phanteks cooler ?
Do Intel chips OC better than AMD chips? The last 3 AMD CPUs overclocked horribly and I never achieved what I wanted. Have I got a better chance with Intel ?


Thank you for any helpful tips!

That cooler will do 4.5 GHz even if you are seriously terribly unlucky with your 3570k, I'm pretty sure.

You might want to look at a Gigabyte GA-Z77X-D3H for the board. You should be able to get it for the same price, probably cheaper than the Extreme4. The pricier GA-Z77X-UD3H is a very similar design, just has buttons and whatnot.

Without a lot of overclocking, you'll probably have a better experience with ASRock from what I've seen comparing the BIOS and boot times, mysterious problems with Windows drivers, things like that. That's just my personal opinion.

If you overclock as much as possible, the Gigabyte board will do very well. At the least, it'll stay cooler. I've also seen my CPU going 0.1 GHz more with the same temperature after zoning in on the perfect voltage compared to ASRock. It's likely I did something wrong as that story sounds strange. As an explanation I speculate the Gigabyte provides "cleaner" voltage, more stable or something.

The ASRock is also flexing a lot. You could describe it as flopping around if you lift it and move it. I think the Gigabyte is straight up thicker.

You should also try to research something about the other brands.

About the CPU cache size, the i7 has 8 MB so you can use its performance to compare. It seems to not make much (any?) difference in practice. You could look at benchmarks, but I don't know how much of the differences are caused by the cache size, and how much is because of HyperThreading.

About the number of cores on the AMD, the cores of Intel simply are faster, and the AMD cores are not complete. Each two AMD cores share one FPU, so they can't do those instructions in parallel. This is the same limitation Intel's hyperthreading has, though it's only for those special instructions. Still, one Intel core with hyperthreading is probably not terribly different in practice compared to those two AMD cores. Again, if you look at benchmarks, the i5 is not far off with most stuff.

The i5 is also a lot cooler than i7. That's from hyperthreading being off. You get about 10 C lower temperatures. Because of that and overclocking, it's a very good choice even if you use software that could make good use of the i7. If it's mostly about games, the i5 might be better even when disregarding the price.

For your question about overclocking, it's definitely a lottery. You might get a good chip, or you might get sad.

None for nothing, you have an 990FX board already. Grab a 8320 or 8350, a Corsair H100, overclock to 4.7/4.8GHz and call it day (this really shouldn't be a problem at all). If it's for gaming spend your leftover money on grabbing a better GPU.

Look at this way:

You can get an FX8320 from Amazon.co.uk for £120.98

You can get an open box H100 for £70.69

That totals to £191.67

With your £400 budget, that leaves you with £208.33 for a graphics card:

So grab a Sapphire Radeon HD 7870 GHz Edition for £183.00

The 8320 will overclock well, it will be slower than the 3570k in a lot of situations but it won't really be that bad considering what you already own. At 4.7/4.8GHz it will be pretty close to at least a 2500k which is really nice. With the H100 it will keep it pretty cool, so that overclock should be fine. Then you get a better graphics card than your 560Ti, and if you go Crossfire later you will be quite pleased. After all, this is for gaming.

This is the best option considering your circumstances.

The budget of 400 requires me to sell my motherboard and 1090t along with 4 Gb of RAM (+ an old rig that is already on ebay).
If I stay with AMD I'll have about £250 to spend.
+ I can't fit an H100 in my case and even if I did, I would have to use slim fans with less static pressure so I'd lose cooling performance. I'd still have to get the Phanteks.
