Upgrade From I5-3570k To A I7-4790k? Few Questions

[fl-gators-fan]

Hi guys

I've been thinking about an upgrade lately. I currently have an I5-3570k @ 4.0 GHz with an Asrock Z77 Extreme 6 motherboard. Everything with my gaming rig is amazing, but I currently have enough funds available to upgrade my system, and it's burning a hole in my pocket....lol! Whenever I have extra funds available my first option always has to do with computers.

My question; is my Corsair HX750 enough to power an I7-4790k with a small OC, X2 GTX 770s in SLI, a new Gigabyte Z97X Gaming GT motherboard and a Corsair H100i liquid CPU cooler?

Right now my system consists of the following (copy and pasted)

NZXT H440 all white case with x3 NZXT 120mm fans in the front as intake & x1 Corsair AF140 quiet edition fan in the back as exhaust

Corsair H100i all in one liquid CPU cooler with x2 Corsair SP120 high performance edition PWM fans (exhaust)

Intel I5-3570K Ivy Bridge CPU overclocked to 4.0 GHz @ 1.125 volts (fixed voltage)

ASRock Z77 Extreme 6 motherboard

16 GB (8GB x 2) G.Skill Ares Series DDR3 1600 RAM

x2 EVGA GTX 770 SC 2 GB Video Cards in 2 way SLI

Corsair Professional Series HX 750 watt 80+ gold PSU

Samsung 840 Series 250 GB SSD drive (Games)

Mushkin Chronos 120 GB SSD drive (Primary OS & programs)

Hitachi 1TB 7,200 hard drive

Windows 7 Professional 64 bit

Cooler Master CM Storm Devastator Gaming Keyboard

Cooler Master CM Storm Devastator Gaming Mouse

Roccat Sense Chrome Blue Gaming Mouse Mat

AOC Q2963PM 29" Ultra Widescreen IPS monitor (2560x1080)

GX Gaming SW-G2.1 2000 gaming speaker and subwoofer set

x2 EVGA Pro SLI bridges

Any help would be greatly appreciated and like I mentioned I'd like to do this as I have the necessary fund available. I don't however have enough for a new PSU to go with it though.

Thanks for any & all help!

my 2 cents, save it. yes i know it's hard to resist the itch, i have the sickness as well. Also, cpu's tend to stay longer (we can easily oc them beyond 4ghz) compared to gpu's.
you already have a very good setup, save it. then build a better one next time

the psu should be enough yes

I agree, save it. The extra CPU power isn't going to have a significant enough affect on your gaming to justify dropping that kind of coin. Wait until you can make an upgrade that is less lateral.

If your PSU is doing the job now, then it'd still do the job if you made that upgrade, but I'd personally want a little more headroom on my PSU

/agree save your cash. I'm still getting better than stock haswell performance out of my 2500k. If you were deeply into video editing and streaming it might be convenient to upgrade but it's a gaming rig so no.

Your next upgrade should be a few years from now, probably in the 4k direction when it's been refined.

Well you'd need to get a new motherboard too since the 3570k is LGA 1155 socket and the 4790k is LGA 1150 socket. If you were wanting to keep the same motherboard you'd be looking at the 3770k. In either case the performance increase would be negligible for gaming so unless you do HD editing or rendering it's not worth it. Keep your money still Skylake comes out next year, probably still wouldn't be worth it but at least there should be some performance increase.

Thanks everyone!! I appreciate all your input. It's really not like I need the upgrade, but the idea of having my first I7 CPU with a pretty decent motherboard has got my interest hooked

Would having a motherboard with duel PCI-e x16 lanes be better then my current 8x8 setup? The Z97 Gigabyte board I mentioned in my post supports 4 way SLI and 2 slots at 16x16.

Nah, you're fine. x8 or x16, irrelevant in this case.

Remember, i7 is just a name. It does no fancy voodoo.

You're solid for the next year or more til newer innovations (hopefully) start to take hold.
