Hi all,

I'm currently looking at a completely new build very similar to the System Builder Marathon, Sept. 2010: $1000 Enthusiast PC. (Core i5-750, GeForce GTX 470)

Could that overclocked i5-750 handle an additional GeForce GTX 470 in 2 years time (provided I buy an SLI ready motherboard) or is that CPU not powerful enough? Is it worth spending an additional €200-€300 (or $200-$300) on an i7-930 (and a motherboard, memory and slightly better graphics card to go with it) to increase the longevity of the system or should I spend the money on hookers and booze instead?

Is buying now actually a good idea, or are new architectures and sockets from AMD and Intel worth the wait till 2011?

More about : lga 1156 lga 1366 wait till 2011

That's a tough choice!

I'd get the 1366 system if your current system is hopeless otherwise I'd wait for 1155. If the ram price concerns you get 4gb in real life you won't notice a difference.

and about pc vs booze and hookers?

a tough question indeed

The i5 performs better perclock than the i7 in the majority of games, so I'm tempted to say yes.

There's always something new coming out next year. The question is, do you need to replace your computer now? If your current one is dead for example and you need a replacement then get a new one. If you've got a decent system, already and wanna just spend more money for not particular need, then no.


Also, don't build to SLI 2-3 yrs down the road. There will be new better stuff by then. If you plan to add a second GPU in a year or so, then yes do it.

Also, is this a gaming or workstation build? For gaming an i7 really is pointless unless you plan on using 3 or more GPU's.

That is the most solid and succinct advice I have ever seen covering all of the important points of "buy now vs. buy later".

1) If you can wait, wait. If you can't wait, then clearly you should buy now.

2) I would guess that the majority of people who include SLI/CrossFire capability in their builds never use it. By the time most people need/want another card, something better has come along.

3) It's strange to see how many people want an i7 just to have an i7. Games don't need hyperthreading. Games rarely need multi-GPU setups.

Although I'm a fan of making sure your build is future-resistant, you should buy what you need when you need it. Don't buy a ton more than you need, especially when you don't need it yet.

IMO an i7 930 is a powerful basis for a powerful gaming pc and thus I like it. Your cpu will hardly ever be an issue. The reason I reccomended to go i7 is because of the upgrade path to multiple GPUs and a 980. But I suppose if you're shelling out that much an upgrades it won't hurt to buy a lightpeak supporting native 6gb/s mobo aswell.

I find hyperthreading a pretty useless feature really the benefits are extremely minimal.

So yeah follow the above advice.

You may as well wait a few weeks for LGA 1155 and Sandy Bridge. While Bulldozer isn't expected till early next year, Sandy Bridge is suppose to come out in Q4. It's up to you
September 7, 2010 9:09:16 PM

An i5 750 and a GTX 460 are all you need for gaming at up to 1920 resolution.

I don't like the term "future-proof", so let's say to allow room for expansion:

1) Buy a mobo that has 2 PCIe 16 slots and supports SLI. A second slot running at X4 or X8 is good enough, so don't spend a lot of money (to get X16-X8) on this piece of "insurance".

2) Spend a few dollars more on a 550W PSU, which is enough to support 2x460.

You'll be rewarded with excellent gaming (if at 1920 or lower), and the ability to add >50% FPS if/when needed by adding another 460. Your PC will also be cool and quiet.

550 is only enough if it's a premium Corsair/XFX/Antec, and even then you can't run Furmark like that. In my opinion 650 is the minimum for 460 SLI (with room for degradation and Crysis), and 750 would be peace of mind.
September 7, 2010 9:20:33 PM

Yup, you need to buy a 550W unit that actually is a 550W unit.

To confirm power requirements, the link below shows a 980X OC'd to 4.0GHz driving 2x460 using 480W at the wall for the entire system while under full graphics load:

http://www.tomshardware.com/reviews/geforce-gtx-460-sli-geforce-gtx-480,2694-10.html

That PSU is providing less than 430W to the system, which leaves more than enough room for a 550W to max an i5 750 simultaneously under full load . . . a condition that is unlikely to be reached in the real world.
September 7, 2010 9:48:46 PM

^ Agreed, at least quality 600W if going to do any OCing/SLI 2x 460s.
September 7, 2010 11:19:10 PM

Thx for all the advice, guys.

(Should have mentioned that I've already bought a 750W PSU a few month ago when my old PSU died. No need to argue over PSUs :lol:  )

I've now discarded the i7-930 idea.
I will either build a new machine with an i5 and an SLI ready motherboard next week or keep my current machine going till Q1 or Q2 2011.

My current machine (Core 2 Duo E6750 @ 3.2ghz, slightly overclocked 256mb ATI HD 3850, 4GB DDR2-800) is really starting to show its age now, especially with my new 1920x1080 display, but I guess I could live with it a bit longer.
The release schedule isn't looking that great anyway. Shogun 2:TW is still far away :cry:

Your bottleneck is the 3850. Consider 100$ on a 1GB 4870/GTX 260.

In my opinion I would wait for Q1 (or at least Q4). That would put you into Sandybridge+ATI 6000 series launch dates.
September 7, 2010 11:29:57 PM

Agreed. If you are going to OC the graphics cards, as were used in Anand's 528W bench, 650 is a good idea.
September 7, 2010 11:34:46 PM

Those weren't OCed though?

+1. Q4 isn't that far away and ATI is suppose to release their 6xxx cards, which should drive down 5xxx and 4xxx cards down. 4870 CrossFire may be able to be had for ~$150-200 :D

Now let's get back to the booze and women - I'd spend 99% on booze and women, and the rest I'd spend foolishly!
September 8, 2010 1:32:33 AM

wait it out if you can
September 9, 2010 2:51:08 PM

I've now bought a 1Gb ATI HD 4850 for 95€ and it really made a huge difference. Thx for the advice.

This will most likely keep my machine usable till the middle of 2011.
