Ok so Im gonna revamp my old rig (and by revamp I mean the only thing Im keeping is my DVD burner.)

If anyone knows something I dont (very likely) and sees an area where I could spend less than or equal to the money and get better performance, let me know.

8800 GTX 768mb (PNY) $549.99

2x1gb Gskill DDR2 800 RAM, timings are a tight 4-4-3-5 $199.99

AMD Athlon 64 X2 5200+ 2.6Ghz processor (2x 1mb L2 cache.) $229.00

Gigabyte S4, socket AM2 Nforce 4 motherboard (built in RAID controller, 4 RAM slots, 1000 Mhz hyper transport front side bus. $88.99

2x 160gb SATA 3.0 Gb/s hard drives (Western Digital). $105.98 (for both)

Already have 550 watt power supply and case.

Any suggestions? Oh and no "get an intel cuz AMD sucks" posts please. I dont care, the 5200 is an awesome processor for the money.

Hey, it's your money to burn, if you want AMD go AMD.

Also if you wanna burn money on the GTX then do that too. Unless you're gaming at 24" or greater, the GTS will do.

Check your PSU, make sure it has enough amps on the 12v rail(s). 550w doesn't mean it's enough....it's not the wattage per se, it's the amps.

Ever consider EVGA or MSI?

Mind specifying the power supply? Amps on the 12v matter more than the wattage.

Not to sound fan-boyish here but to get the most performance out of a GTX you need a faster CPU. (http://www.tomshardware.com/2006/11/29/geforce_8800_nee...)

Anyway, my only worry is the PSU. How many amps on the 12v are we talking, here?

5200+ X2 is still the better choice for arithmetic.

What's the PSU brand & model?

http://www.gigabyte.com.tw/Products/Motherboard/Product...

Looks like Gigabyte learned where to put the SATA/USB connectors. My DQ6 has 4 SATA connectors totally covered in GTS/GTX SLI.

You can get the same brand same speed ram for less if you buy from newegg. Unless you have a reason for that specific ram.
March 11, 2007 10:41:39 PM

WOW! Giga finally got smart!!! It's about time someone used common sense.......now, if only they learned to rotate the SATA ports by 90 degrees to help in cable management to tuck behind the hard drive cage. And then lay the IDE headers flush with the board for the same reason :roll:

I want one......too bad it's not S775. :( 
March 12, 2007 12:31:41 AM

Yeah, the PSU will handle it, I already made sure.

Thanks for the input. The 5200+ wont be a major bottleneck will it? I dont really mind a few fps, just major slowdowns.

Oh, and akhilles, the RAM is priced from newegg, must have dropped the price even more! Badass.

Thanks guys.
March 12, 2007 2:02:42 AM

The 5200 shouldn't bottleneck at any decent resolution. The higher the rez, the more GPU-limited, not CPU. Play higher than 1024 rez and you'll be just fine.

You have the money for a GTX but not for an ASUS Crosshair? Get the Crosshair. OCZ DDR2 800 is better. I have my Platinum Rev.2 running at 940MHz with 4-4-4-12. Don't skimp on HDDs.

P.S.

I think you'll do just fine.But like others have said,the psu gives me some concern.Now I know you werre told it would do the trick,and that may well be.But for how long?is the question I ask.Build it as is,but please consider buying a bigger and better psu as soon as finances allow for it.Seriously dude,you don't want the psu crapping out and taking the whole system with it.It is just my thoughts.I've seen it happen before.I look at it kind of like rebuilding a motor.Your original oil pump might be working fine now,but it could and most likely will fail at the most in-opportune time.Goodluck.

Word to that. I have had that happen before (PSU takes the system with it) and it sucks donkey balls man. I would definately buy a better PSU. Even 520W Corsair which is inexpensive but an excellent PSU.

Thanks for the advise, question though. Whats so good about the ASUS Crosshair? Not that I doubt you, just wondering.

Oh and I dont intend to overclock anything in this system, so that said, anything else?
March 12, 2007 4:06:11 PM

For gaming on an AM2 mobo there is no better. There is not much difference between the nForce 590 chipset mobos (AMD) which means that you start looking for bells and whistles as well. The crosshair has been reviewd as one of the best AM2 mobos and I agree 100%. I love it. Great for OCing and gaming. Plus it looks awsome.

Ok, update, here is the PSU for the system. Sorry I couldnt find it for a while.

Rosewill 550 Watt
ATX V2.01 Dual 12V rails
+3.3@30A, +5V@50A, +12V1@18A, +12V2@18A, -12V@1A, +5V SB@2.5A
SLI ready
20+4 pin main connector
Over voltage protection :) 

Anyway Im pretty sure it'll do the job. Am I right?
March 13, 2007 8:15:50 PM

Check this out for an explanation on PSU's. Also, go to the bottom and click on PSU Rankings.

You will see that Rosewill is one of the worse brands there is. 32A is what's recommended for the 8800GTX. You just can't add up your 2 18A rails. There is a maximum amount of watts that will be supplied if your 3.3V & 5V rail use up the maximum wattage allowed to them.

Take this "maximum" wattage and divide by 12 to get the minimum amount of Amps supplied across the 2 12-volt rails. This will determine if your PSU is capable.

My take on getting the 8800GTX is not to get it. I believe it would be better to get an 8800GTS with 320MB and get a new PSU. Get one that is very efficient as cheaper electricity bills will in effect pay for a better quality PSU. The Seasonic S12 Energy Plus or Antec NeoHE 550 should be on top of your list.

My previous 2 computers were AMD. I just build a new computer around the E6400. Mainly, because I bought it for $160 (OEM) and it's oc'ing abilities will make any AMD CPU cringe.

If you don't plan on oc'ing, then the 5200 is a good chip. AMD needs some support so that the Intel/AMD war continues until the next millenium. ;-)

Read that article mentioned by the other poster concerning that the 8800GTX needs the fastest CPU. I think the article speaks for itself.

I'm not going to deny that the Xhair is a nice mobo. It looks "cool" and oc's good for AMD chips but the price tag on it is simply outrageous. And you are not going to oc an AMD chip to that of the level of a C2D. I don't care what mobo you have.

I recently purchased the Gigabyte GA-965P-DS3 and it oc's very well from articles I've read. I've only mildly oc'd my E6400 from 2.13 to 2.4 GHz as I only have the stock heatsink (which sillyrabbit graciously gave me) and my PSU was stock with the Antec Sonata II case. The PSU isn't the greatest but for my current system without oc'ing, it'll do just fine.

I plan on getting the Noctua NH-U12F. It's going to cost me around 73 bucks but to have the chance of oc'ing my E6400 close to 4 GHz on air cooling is well worth the cost. And the PSU I'm going to get is the Seasonic S12 650W version.

If you plan on oc'ing, I'd stick with the C2D as it's the best price/perf CPU out there.

Do I hope that K10 sinks Intel C2D? You betcha. Because Intel will have to counter making all the system builders here very happy.
March 13, 2007 11:37:16 PM

So...

Is that a no?

or a yes, but I wouldn't recomend it.
March 14, 2007 10:36:36 AM

Without you giving the specifications of the the PSU or the exact model number, I can't answer that question.

Look at the back of your PSU. Check out what the max watts supplied to everything other than the 2 12V rails. Subtract this number from 550 then divide by 12 and you will get the minimum supplied A to the 12V rails.

Take, for example, this Seasonic S12 Energy Plus 650W PSU.

The maximum wattage for the other lines is 195W but I will round up to 200. 650W - 200W = 450 W / 12 V = 37.5 A minimum.

If you take a look at the back, it says it will supply 52A max. It has 4 rails at 18A each. 4x18 = 72A. So, the PSU does not actually delievery the maximum A across the rails that should be available and 52A is a far cry from 37.5 A being the minimum.

Now you have the tools to determine if your PSU will work.
March 14, 2007 1:06:58 PM

Ah yes, w/v=a, back to physics class. Ok that explains it quite well.

Thanks for your help.

Ok, I have a question:

What is then "correct"? That it can supply 4x18? Or that it can supply 52A max and 37.5A is the minimum?

How does the 4x18 correlate to the 37.5 and the quoted 52 max?
March 14, 2007 4:11:17 PM

The PSU can only supply 650W.

650W/12A = ~54A

Obviously, because of the power limitation, the PSU cannot put out all of the Amps that the 4 rails can handle, 4x18A = 72A.

The maximum of 52A stated is probably based on the minimum watts being sent out to the other lines.

But since the other lines will not always use the minimum watts, I like to err on the safe side when it comes to PSU's.

I calculated 37.5 A as a minimum. You know for a fact that the PSU will always give out 37.5A as long as it's functioning properly. You may get as much as 52A as the PSU states, but this is completely unreasonable as the other lines will definitely use up some power from the PSU to make the Amps going to the rails go down.

Even though I calculated 37.5 A as a minimum, I would believe it safe to assume 40A as a minimum.

Btw, another GTX manufacturer only recommends 28A for the GTX. So, Curmudgeon5462, if your PSU supplies a minimum of 28A, I would say you are good to go.

Thanks for the explanation Purdue....makes sense to me now.


Much appreciated.

Thanks indeed. All is clear now.
