Znam da mi procesor na igra ulogu u bitcoinu,najbitnija je grafika. Sad gledam da ako stavim tri 7950 da napajanje moze da mi bude problem. :( Ne znam sta da radim,a mislim da mi cak ni Seasonic od 850W ne resava posao.A nemam nikoga preko inace bih uzeo Enermax,Seasonic ili Tagan od 1 KW ili cak malo jace..

Pa i ti nisi naivan,znas i ti sta valja..Hoces da napravis masinu da se naJEZ(a)IS Trebao bi taj Seasonic da odradi posao ali u pravu si,od viska glava ne boli,bolje je kad je napajanje manje optereceno.. Ovde si osudjen na CM..Sta znam..Radio sam malo na CM Gold PRO 1200W ,unutra je Enhance,napajanje je dobilo visoke ocene ,ja sam zadovoljan..Nije Seasonic ni Enermax ali je sasvim korektno..

Da, zato mi je to i nadimak. Mislim da ce mi drugar doneti Seasonic 1000W, Seasonic P1000, pa cu onda tako resiti sve muke, mislim da ce biti dovoljno za moje potrebe. Ne bih bas isao na CM, nekako nemam poverenja u njih posle ovog mog Seasonic-a.

7950 donese oko 40e ako se ne gasi mesec dana , bukvalno dan noc.
A sa nvidijom mozes da se slikas...
Why are AMD GPUs faster than Nvidia GPUs?
Firstly, AMD designs GPUs with many simple ALUs/shaders (VLIW design) that run at a relatively low frequency clock (typically 1120-3200 ALUs at 625-900 MHz),
whereas Nvidia`s microarchitecture consists of fewer more complex ALUs and tries to compensate with a higher shader clock (typically 448-1024 ALUs at 1150-1544 MHz). Because of this VLIW vs. non-VLIW difference, Nvidia uses up more square millimeters of die space per ALU, hence can pack fewer of them per chip, and they hit the frequency wall sooner than AMD which prevents them from increasing the clock high enough to match or surpass AMD`s performance. This translates to a raw ALU performance advantage for AMD:
AMD Radeon HD 6990: 3072 ALUs x 830 MHz = 2550 billion 32-bit instruction per second Nvidia GTX 590: 1024 ALUs x 1214 MHz = 1243 billion 32-bit instruction per second
This approximate 2x-3x performance difference exists across the entire range of AMD and Nvidia GPUs. It is very visible in all ALU-bound GPGPU workloads such as Bitcoin, password bruteforcers, etc.
Secondly, another difference favoring Bitcoin mining on AMD GPUs instead of Nvidia`s is that the mining algorithm is based on SHA-256, which makes heavy use of the 32-bit integer right rotate operation. This operation can be implemented as a single hardware instruction on AMD GPUs (BIT_ALIGN_INT), but requires three separate hardware instructions to be emulated on Nvidia GPUs (2 shifts + 1 add). This alone gives AMD another 1.7x performance advantage (~1900 instructions instead of ~3250 to execute the SHA-256 compression function).
Combined together, these 2 factors make AMD GPUs overall 3x-5x faster when mining Bitcoins.
Racunam sad nesto kad odbijem cenu za sruju i internet ulozene pare za opremu profit (ako je ovo 40e tacno) dobijem da za godinu i po dana se isplati oprema.

izvadi kartu, drzi je rukom u lepom vodoravnom polozaju, drugom rukom udari shrafove i onda ce da ostane kako treba, nema potrebe da ti se krivi taj slot tako, greota.
@Dex Znam da se krivi :)) Probao sam i dzaba, probacu opet.. Nesto imam utisak kao da nije dobro utegnuta, a ASUS se drzi samo tako iako je duplo teza graficka.. Lepo me greju u ovim zimskim danima,taman ustedim barem sto se pecke tice. :D
@djokosrb Kod mene cooler radi na 80%, malo tako nekad zna da divlja, a ASUS opusteno duplo manje.. Ma kupio sam je zbog grejanja,kazem ti da mi je tako jeftinije. :D

Moj poznanik od koga sam kupio par grafickih karti za neke prijatelje i rodbinu, se ozbiljno bavi rudarenjem. Soba je samo za ovo, 3 klime udaraju , nista se ne gasi 24/7. Ozbiljno ulaganje ali se vrati kaze posle 6 meseci sve.
