PC na pracovné účely

Chcem si kúpiť nejaký PC, na Intel platforme, a s dobrým chladením.
Potrebujem zostavu čo s najlepším pomerom cena/výkon, a možnosť rozšírenia v budúcnosti.
Nič náročné, grafická nejaká slbšia, ako keby na kancelárské účely avšak potrebujem niečo také aby nebolo lenivé a cena max. 18tisíc..

Ale to 18tis. aj s monitorom?

Nie bez monitora...

VGA integrovana, ASUS P5E-V + E8400/8200 + freezer7 + 2GB ram + 400W fortron (pre pripadne dokupenie VGA zatial staci alebo 450) + HDD 320/250GB + skrina a DVD mechanika

Nemyslis, ze ta E8400, pripadne 8200 mu je zbytocna??? Podla mna aj nieco lacnejsie by sa naslo...

Čo myslíte Asus HD3650, alebo Sapphire HD2600XT, tú 2600vku mám o 150SK lacnejšie..
Tú 8200/8400 no nad tým rozmýšlam, ale ešte potrebujem nejakú doksu do max. 5,5l s dobrým možnosťami budúceho upgradu..

Ta asuska neni zla ale ak chces dobru MB do buducna tak GIGABYTE X38-DS4 http://www.alza.sk/gigabyte-x38-ds4-x38 ... d85916.htm 5643 SKK, tu asus som tam dal kvoly integrovanej VGA ale ked hces kupit ATINU tak voala E8200neni vobec zbytocne praveze stoji okolo 5200 a da sa zohnat na rozdiel od E8400

V pondelok mmá E8400 doma za cenu 6000SK s poštou, myslím, že to je OK, a keď tak rozmýšľam pôjde to terajšej PC zostavy, a E4600 do tej novej, myslítw, že by to bolo OK???
A ešte 2600XT alebo HD3650??

A vlastne ako vizera ta nova zostava s tym E4600? VGA by som dal skor 3650

Ak myslíš tú čo mám zatiaľ zostavu v podpise, tak zatiaľ šlape fajn. Snažím sa nájsť hranice OC, toto už bude asi max. ešte jedine s VGA sa pohrať..
Dík,tak že objednám tú HD3650..
Na koľko by sa dal dať E8400, s touto zostavou čo mám v podpise..

pche, na x38 ti pošlape aj na 4,5GHz, ak sa posnažíš...

Na pracovne ucely ti postaci hoci co.

Mno realne to aj (co som cital tak ze pri vacsom OC sa rapidne zvacsuje teplota E8400) je aj ked 3,5 GHz je uz ulne postacujuce..

v dnesnej dobe ti uplne na beznu pracu postaci dvojjadro na 1,8...kolkokrat denne konvertujes, komprimujes?....osobne pri beznom uzivani nepocitim rozdiel pri 1,8 alebo 3Ghz...ani pri Viste....jedine pri hrach je to citit a spominanych operaciach...takze mat nonstop procak na 4 - 4,5ghz je v podstate na dve veci aj ked potesi

Normalne ti musim zatlieskat Uplne na beznu pracu staci aj jednojadro..

takto ale tak v praci mame Celeron tualatin 1.3 GHz a to uz je citit otvarat 10Mb excel s 256mb ram je istota ist na kavicku

hej, hlavne q9650

testík:

je to síce qx9650, ale je to penryn
kukajte na to

..dopln aj voltaz, ak je v tom clanku uvedena

Exploring the Limits of 45nm Silicon

During the course of our testing we made a rather interesting discovery regarding 45nm silicon scaling: a window exists in which CPU frequency responds in a highly proportional manner. Calculating this value later tells us that between 3.0GHz and 4.0GHz our processor requires ~0.3mV (0.0003V) more Vcore for each one megahertz increase in core frequency. Since our QX9650 is capable of running the stock 3.0GHz setting at only 0.98V, this means that achieving a stable 3.6GHz overclock requires 0.98V + (0.3mV/MHz)(600MHz) = 1.16V. This general trend continues all the way to about 4.0GHz where we found total stability at an amazingly low 1.28V. We cannot help but feel excited about Intel's new 45nm process, especially considering such early maturity.


Always target the higher end of the Proportional Overclocking Region


Dropping below 3.0GHz allows us a chance to experiment in the world of low-voltage (LV) and ultra low-voltage (ULV) clocking. Two point four gigahertz (2.4GHz) was possible at only 0.90V. Additionally, the lowest possible core speed that we could dial-in using the ASUS P5E3 (6 x 200MHz = 1.20GHz) had no problems maintaining stability at only 0.81V. It's interesting to note that this is also the lowest Vcore we could supply the CPU, as VID settings below 0.85000 were not available for use. As an aside, the VRM 11.0 specification, used extensively by motherboards supporting 65nm CPUs, calls for selection values down to 0.70000V.

As expected, pushing the QX9650 above 4.0GHz, although possible, also demands more Vcore than predicted by our simple scaling equation. In fact, running well in excess of this speed requires a nearly exponential increase in voltage. At this point gains are small and generally not worth the extra heat produced because of the excess power consumed. Clearly, the more efficient silicon switching that comes with better cooling is needed if we planning to go much higher. Oddly enough, for the first time in water-cooled quad-core history, we feel as though heat is not the limiting factor. Rather than push this finding aside, we decided to examine the cause a little more closely.




We start our investigation by comparing our measured processor power consumption values with those found through use of the well-known power scaling equation (shown above). The equation wonderfully predicts what we see at lower frequencies but quickly falls behind actual measured values when looking at higher speeds:

4GHz na 1.28 voltu... super

velice vydareny kus, potom uz je ta spotreba jasna, osobna ma zaujali hlavne nizsie hodnoty, 36W pre 2,4GHz quadcore by pre notasy bola velice akceptovatelna hodnota, a 1,2GHz ani nevravim, dualcore s podobnym napätim by mohol byt velice dobry riesnim pre notasy

No ved nie len pre notasy Uz len cena tam je najnegativnejsi faktor

tak ale cena je takalen preto ze je to XE a tam je jedinym rozdielom odomknuty nasobic

ty kokso, keď tak pozerám dajme tomu, že 2.4Ghz bude zákl. frekvenia mojej E4600vky, teraz ide na 3,8Ghz (353*11)...to tak rapídne sa zvýši i spotreba..
aspoň, že mámm 600W zdroj
