Mountain Lion Hackintosh + Hardware Advice + What size PSU?

[Burtalmighty]

Hey guys, basically below is a list of my parts and the prices I can find them for. I'm pretty confident that they're compatible, but should I be considering other parts? Is my chipset okay? Is that a decent graphics card? All advice is welcome!

ALSO
How big a power supply unit am I going to need to power this build? Cheers ​

GIGABYTE GA-B75M-D3V Intel B75 @ ~ £50

3rd Generation Intel® Core™ i5 3470 3.20GHz @ ~ £150

​

i quiet new to the forum my self.

it seems like a nice and buffed machine, except for the GPU so depending on what you want to do on it that might be an area of concern.

 

[Burtalmighty]

See I've had second thoughts about the GPU, but because I'm pretty new to all this myself, I haven't done much about it. Like I said, I'm sure it'll work, but if there are better alternatives for a similar price I'm all ears

 

[mosser]

depends on the price of the 640

 

[Burtalmighty]

the prices are all on my list, but that EVGA would be setting me back about £85

 

[mosser]

i think you are better of with the 650 atleast and theres not that much difference in price

but then again depends on usage. if you are not in to gaming / 3d editing or any graphical intensive things go with the intel hd 4000 on your cpu

http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107.html just find one thats compatible in the price range you want.

but when i build my ealier however as a windows machine for gaming. i decided the AMD 6850 as the standard but then decided to go with AMD 6870 2GB since i should be compatible with os x. and still better performance.

however remember that 7000 series of amd should not be compatible with os x

 

[Burtalmighty]

I do intend to be gaming a bit on this build. I intend to dual boot windows 7 on it for gaming. if the 650's aren't much more expensive I'll look around for one, any recommended brands?

 

[mosser]

from what i understand os x support the gtx 650 out of the box so i would porbally just go for cheapest. but if you want quietness or maybe a higher stock GPU clock go for one that has that.

look at http://www.gpureview.com/show_cards.php?card1=681&card2=636

i could find the 6850 at the same price as the 650 in denmark.

i do like Nvidia more then AMD but the raw power seemed to favor the 6850 and 6870 much more. so i decided that path however its more power hungry.

 

[Burtalmighty]

my GT 640 is 2GB where as a similar priced GTX 650 is only 1GB... shouldn't i stick with the GT 640 for gaming?

 

[mosser]

depends what resulution you are going with.

think of shader cores / cuda cores the same way we think of dual core / quad core in CPU. it not completly the same but i think you will get the idea

the more cores the more horse power.

ram is for textures so if you are in to gaming above 1920x1080 or want to have massive amount of AA / AF on 2gbs might be the way to go but i know that 640 performance is below 650 even with more ram

thumb rule GTX > GT. always as far as i know

gtx 650 = 384 cuda cores and a clock of 1050mhz ish
gt 640 = 384 cuda cores and a clock of 900mhz isn
however this is not the only factor the 640 comes with ddr3 ram and the 650 comes with gddr5 ram which from my understand is 5x times faster then ddr3. the are on the same memory bus 128bit which is fine

however the 68xx series from amd is on a 256 bit bus and have gddr5 ram

6850 = 960 shader cores
6870 = 1120 shader cores

!!! HOWEVER !!! AMD and Nvidia cores cannot not be compared

i would go 650 or 6850 if you can find one and afford one.

could you link the page you are orderring from?
