New i7 build confusion

[adw]

I'm planning to buy this one very soon. specifically for gaming.

+i7 920 DO
+gigabyte ex58-UD5
+2* 500gb Seagate 7200.12 418AS

-- OCZ 3*2GB Gold 1600mhz CAS8 (189$) or
-- CORSAIR 3*2GB 1600MHZ C8 DDR3 TR3X6G1600C8 (185$)
which one would you pick for the same price-same freq-same latency?

and what does 220$ dominator offer? better cooler? (same specs again)


--Zotac GTX 275 AMP 896 MB 448Bit (325$) [@702/1512/2520] or
--Zotac GTX 275 896 MB 448Bit (295$) [@633/1404/2268] or
--Palit GTX 275 896 MB 448Bit GDDR3 HDMI 16X (290$)

Here is the confusion: buy an oc.ed card and oc even further or get the stock one and oc all the way up? the two versions have the same pcb, same chip, same cooler, right? why pay 30$ more? someone enlighten me plz. can't i oc stock one to 745/1600/2600?

And for Palit: i'm unsure about the cooler. quite but hot? it says "tweak it!" on the box, but a little tweak ends up 90+ degree. what's the point?

Cooler Master HAF 932 (229$)
stacker STC-T01 (199$)

does 30$ help the air flow cooler?

here's what i can find for psu:

--HIPER HPU-4M780 780W (205$)
--THERMALTAKE Toughpower XT 750W W0229R (195$)
--PC POWER&COOLING SILENCER 750W QUAD S75QB (184$)
--OCZ MODSTREAM PRO 700W OCZ700MXSP-EU (160$)
--High Power 750W PFC 80+ 14cm (175$)
--SILVERSTONE ZEUS SST-ST75F 750W (150$)
--OCZ StealthXstream 700W OCZ700SXS-EU (140$)

i just want my rig to be stable and let me oc and go sli.


and samsung 2333SW 23' 5ms DVI LCD (252$)

any help, any idea will be appreciated. thanks in advance.

Video card: The pro's of buying a factory OC'ed card is that you are guaranteed that speed (most likely because of a higher binned card) whereas OC'ing yourself is always a gamble. Is it worth it? That's up to you.

PSU: Out of that list I'd go with the PCP&C Silencer.

I'd get the cheaper Zotac. The higher-speed variant is already overkill for your display. In this regard, you shouldn't consider overclocking your video card anymore, to allow for less trouble to achieve stable gaming.

I'd also reconsider 6GB of RAM, only if you're planning to use a 32-bit OS. As you may know, there's a 3.25GB limit on 32-bit Windows.

You're PSU is too powerful. Consider one with 550-650W rating.

As for video cards, I'd go for sapphire's vapor-x/atomic 4890s. 520w corsair is great. Buy 3 GIGs of OCZ ram which have atleast 8-8-8 latency which gives u a OC to 4.0 GHz with i7 920 D0 stepping.

Important, only latency matters for gaming, not frequency neither amount.

Buy a veloci raptor 300gb if you can. Buy a HAf922 which is actually better than HAF932.

A good monitor would be samung p2370 which has LED backlighting.

You could save some money by getting Windows 7 RC.

I would get the PC P&C Silencer if you plan on going with SLI eventually. But make sure you're calculating your watt usage because you want to stick to between 60-80% PSU usage at full-load, but it's OK to be below that if you're not done building your rig (e.g. getting SLI later on). You just don't want to be at 90%+ wattage when you're playing a game or you'll burn it out faster, but the PC P&C is a great PSU and will probably do that for years before you run in to any problems.

I agree with rescawen...go with Windows 7 RC. It's solid enough, works well with games, and it's free for now

The Velociraptor would be amazing in games...faster than RAID-0 7200RPM drives as far as seek-time goes, which is important in games because of the large number of small files that are loaded. But RAID-0 isn't bad either. I've seen noticeable improvements in response time with RAID-0 vs single 7200RPM drives. That part is mostly personal preference IMO (well, all of this is I guess lol).
