I used to have a ton of informations on computers before (1 to 2 years from now) but I am not following the new products so excuse my question
1.I am about to build a new system (my priority is GAMING) so I was searching and I found that core i5 2500K is a good CPU for the money and powerful enough for hardcore gaming is that correct ?
2.what is the CHEAPEST and stil good Gigabyte MOBO that can support it fine(from the box) without any problems or needing updates ? and stil support at least 1333MHZ DDR3 memory ? I don't want any built in graphics ... I will get at least Geforece gtx570
3.Is gefore GTX 570 is a good graphic card or you have any other suggestions ?
4.Is 4GB 1333mhz ram is a good powerful ram for gaming or I should consider 1666mhz or more than 4GB ?
5.How much wattage and what type of power supply should I get for a resonable price ?
The Gigabyte P67A UD3 is your best bet for 1 x graphics card or the UD4 for future Crossfire/SLI. I have the UD4 and love it.
DDR3 1600 cas 8 or 9 is best for Sandy Bridge.
570 is a great card.
2500K is perfect for gaming.
You need a good quality 550w power supply for 1 x graphics card. If SLI is in the future you need 750watts.
Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone ,Enermax or Antec are the best power supply companies.
1. 2500K is a great CPU for gaming.
2. Gigabyte P67A-UD4.
3. GTX 570 is a powerful graphics card, right near the top.
4. I would recommend 8GB of 1600 CL9 RAM.
5. I would recommend Thermaltake TPX-575M or Silverstone ST60F-P or SeaSonic SS-560KM.
Yes, you can use the 1866 memory, but it's really a waste of money. 1600 CL9 is Sandy Bridge's sweet spot.
1. Yes, the 2500k offers the best bang for the buck .... the 2600K seems to have a higher OC ceiling tho ... while only 0.1 Ghz apart at stock I am seeing 0.3 differences in most OC's.
2. The overwhelming review favorite is the Asus P8P67 Pro which is a x8 x8 SLI/CF board. The Gigabyte equivalent would be the P67A-UD4. Here's what Anandtech says in his comparison of the two:
After playing with both boards, I can only come to one conclusion – if it were my money, I would take the ASUS P8P67 Pro over the Gigabyte P67A-UD4. With the ASUS board, you are getting a detailed UEFI, an awesome auto-overclocking tool, better energy saving features, a USB 3.0 bracket , more SATA 6 Gb/s ports, Intel gigabit Ethernet, and in my case, scope for a better overclock. The Gigabyte board is essentially expensive for what is on offer, in terms of usability, features, and extras.
Personally, my fav is the Asus WS Revolution w/ x16 x16 GFX card capability and excellent power / temperature features. It's compared with the Gigabyte P67A-UD7 here:
3. The 570 is a great card .... however it is almost equaled by the 560 900MHz version. When ya consider that the 570 costs $345 (you seem to prefer Gigabyte), the Gigabyte 900 Mhz GTX 560 Ti costs just $215 .... and it can easily be OC'sd to 1000Mhz.
The factory OC'd 560 Ti's perform very close to the 570's. Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game) for the various options (single card / SL or CF) are tabulated below:
In time the difference in price between CAS 7 and 9 should drop when CAS 6 arrives but for now, you will have to decide whether the $50 or so is worth the 2% or so performance difference. In a $2k system, that's a 2.5 % increase in system cost.
5. For any single GFX card system, I'd recommend a minimum of a 650 watter mainly because going any smaller doesn't save a significant amount of cash. The XFX XXX and Core Edition series are the best buy here w/ 9/5 performance ratings
Other choices would be Antec TP New and Corsair TX
If ya thinking perhaps SLI is in your future, for 570's the best alternative is the Antec CP-850. As joinnyguru writes:
It is completely unmatched by any ATX unit on the market I can think of. You'd have to spend twice as much as this thing costs to find the next best thing, performance wise.
But that would need a Antec 1200, DF-85, P193 or P183 case, so the other jonnyguru 10.0 performance rating candidates would be th Antec SG-850, Corsair HX or AX series, XFX Black Edition or Seasonic X series. The XFX model is far cheaper than any of those except the CP-850
Revise your recommendations for Sandy Bridge RAM. It really does need 1.25v/1.35v/1.5v spec RAM, as Intel's warranty is null and void when you use 1.65v RAM, and you really do risk damage to the CPU when running it that high. The useful voltage range is 1.25v-1.6v while still maintaining the warranty.
