Need Help Deciding Between Two Configs (AMD vs Intel)

Postby DerVorleser » Tue Dec 22, 2009 11:03 pm UTC

Well, as the title indicates, I have put together two system configurations for a new PC I'm about to buy.

The main purpose of it would be to play videogames and if it can render those properly it will obviously be able to run a browser, open office and photoshop.

The Intel config:

GPU: Saphire HD 4890 Vapor-X -165€
CPU: Core i5 750 -160€
Mobo: MSI P55-GD55 Motherboard -100€
RAM: G.Skill Ripjaws F3-12800CL9D-4GBRL (1600MHz) -80€
PSU: Be quiet! Straight Power BQT-E7-450W -70€

The AMD config:

GPU: Saphire HD 4890 Vapor-X -165€
CPU: Phenom II X4 955BE -130€
Mobo: Gigabyte GA-MA770T-UD3P -70€
RAM: G.Skill Ripjaws F3-12800CL9D-4GBRL (1600MHz) -80€
PSU: Be quiet! Straight Power BQT-E7-500W -80€ (the AMD CPU needs a bit more power than the Intel one)

Now the question I need anwered is: is the more expensive Intel config worth the premium price when taking future (at least 1.5-2yrs) OC'ing into account? (when I'll need more raw power)

Those two rigs are comparable in performance, maybe leaning in the AMD direction if you don't overclock. Also, the power envelopes are roughly the same, because AMD's thermal envelope is the theoretical ceiling whereas Intel's is a mystery average load; iX chips idle lower than Phenom II parts but their chipsets consume a great deal more power, so... I'd say a 450W PSU is fine for both builds.

Since the AMD build is so much cheaper, why aren't you getting an HD 5850? That's your real performance limiter. It also consumes less power than a 4890.

The problem with the 5850 is that the cheapest one available to me costs 300€. That's just too far over my budget, even with the 50-60€ I save by using the AMD setup.
The thing with the overclocking is, I will be doing it in about a year in order to keep up with new standards. So it'd be helpful to know which config can offer me the most power when oc'd to the max later on (with a proper cpu cooler obviously).

OK, then get two HD 5750s, those sell for about EU110. You'd have to change motherboards, though. In my tests, two 5770s are comparable to a single 5870, I suspect the same is true for the 5750.

And like I said, out-of-the-box, I'd expect better gaming from the AMD processor. Overclocked, the i7 will be faster. I'd overclock either from the start, anyway. You can probably hit 3.6 with the Phenom II and 3.0 with the i7 without even upping the voltages.

To be honest I think it's be much safer to be using a 500 - 550W minimum PSU if you're gonna be running that card.

I can't imagine any of the above setups being able to peak draw more than 350W, for serious.

Price/performance-wise, the two builds are essentially the same: if you think you can afford the extra dough, get the i5, otherwise stick with the x4. I don't know anything about overclocking i5's, but I've heard of people running X4's over 4.0Ghz on custom cooling setups. Either system should easily handle anything on the market today, and the near future.

This is, for some reason, one of the funniest things I've read today.
