I am running the same components. CPU overclocks beautifully.
On this note, well this is true as of when the processor came out, not anymore most likely; but the Pentium G3258 from Intel was unbelievable, you could buy a cheapass heatsink for it OC the living crap out of it. This is of 2015 tho, as of now AMD has the lead across the entire board
Tell it how it is
i have an r9 fury my phenom 2 1100T bottlenecks it obviously because I should not be getting 40 fps on bf4 with this card will an i5 4690k lift the bottleneck or should I go for the i7 4790k?
that is an I series, I was talking about the msi-m series, I have not used I yet, however, by what that guy says sounds promising, but at the time, asus z97 -a was a much preferable choice, since the price was low (now higher), and offered a bit more than the m series, which was more expensive.
WTF is your problem with MSI?
You're a poor, AMD fanboy who still thinks that AMD can do any better than Intel (but hey, I'm waiting for Zen vs Skylake/Kaby Lake)
If you can't afford a $229 cpu then maybe you shouldn't be gaming?
do not go for the GTX 960 dude. you made a good choice for the cpu but that gpu is going too be bad, the memory bus is small which makes the 4GB VRAM a waste. and games are starting to require more VRAM so go for the R9 380 or R9 380x. the 380x is on sale for like $200 on or $196 if you waive free return. Or you can get the R9 380 on newegg use the 15NOW discount code on for the discount on the gpu. just i'm telling you man, don't go for the GTX 960. You probably already did since it was 5 months ago. I5-4690k is good choice tho. i recommend AsRock Z97 Extreme3 motherboard. its going for $82 i think.
Threads only prepare information to be processed by the actual cores, on this way rendering would go a lot better. But in games there is not that much of a difference (And this will probably stay like that), also they have the same architecture (Haswell). So if they are clocked at the same frequency they would make the same amount of instructions. So if the i7 4790k beats the i5 4690k in gaming, this is only caused by the higher frequency the i7 is running at. My tips as a stupid 14-year old: Just overclock your i5, it's an k version anyways.
np, just trying to help out, ever since it seems msi do not put down their prices after more better ones come out, would have been the best about 1-2 years ago, now it is quiet outdated, and burns out quickly when paired with the i7, late i5
Thanks, I'll get the z97-a
would re-think msi, but if you are looking for looks over performance, then go for it, but I would reconsider trying to get a gigybyte series, or an asus, I know these are big companies, but the boards they sell are now more game ready then most smaller companies, which is sad, but is an unavoidable fact. with the gpu and cpu problem, can you tell me exactly what you mean? like,, if you are saying 'should I put it together the i7 with the GTX 980?' or 'would the GTX 980 go better then other GPU's on the market with the i7?'
I would re-think using the MSI Z97-GAMING 5 ATX LGA1150 Motherboard, even though it looks good, it isn't worth it's price, I would say, about 80-90 pounds pushing it, I would suggest getting the asus z97-a (or you can get the asus z97-p, but some the screwing are a bit dodgy, but this only effects you if you want it to look good and if you have a weak heart) with what you are getting, round the same price, and has been modified for both casual and gaming use,and it is the round the same price, with lot's more features which you need then that one.
I want to buy an i7-4790 with a nice MSI M-Power MoBo but the GPU will hold it back. I have a habit of maxing out one thing without the other. Like a GTX 980 or an i7
£450 for those two, my budget was £800 but i don't need to buy everything new because i already have storage and a good psu. my pc in the making -
How much did it run you? I need a new mobo and PSU to run anything better. My budget is fixed at $550, I am trying to get a good mobo and an i5 4690k with GTX 960.
*Cough cough* Just bought gtx 970 g1 and the i5 4690k
I'm stuck with a shit FX-4350, do you think I should updgrade to Skylake i7 or upgrade the GPU which is a GT 730
Agreed. I spent 4 years, 4 years too many on a fx-8350. The difference with my 4790k is like night and day in cpu bound senarios. Take skyrim for example, possibly the most cpu bound spot in the entire game, the steps of Whiterun ( Dragonsreach) looking down. 30fps on the FX....over 50fps on the 4790k. You get what you pay for. In anything cpu bound, FX's choke, it's pathetic. A lot of the time the difference between Intel and AMD is between little to none as the game is GPU bound. The rest of the time....lets just say I finally ditched my fx-8350 because of the rest of the time. AMD's current cpu's suck.
You do realize hyper threaded threads are maybe 20% of a real thread and that would be exaggerating /over estimating right? With that being said I stand by what I said. Hyperthreading threads aren't real cores. and if hyper threading isn't utilized your i7 is a glorified i5.
Not in the long run. Games will soon start utilizing 8 threads, which i5's only have 4
opinions, allow people to have them without bashing them
poor guy, i am sorry for what happened to you ROTTEN FCKING BRAIN
