I've been looking for the graphic card I can get the most preformance out of for this resolution. I'm making an all new build and i've been trying to find an GPU setup that would allow me to play games at there max settings and maintain a very good FPS. I understand that 1440x900 is considered a "real" gaming resolution most of the time but its the size i prefer to use my computer at and I don't like using my computer on very large screens.

Heres the rest of my setup as planned so far:

Heatsink - Xigmatek HDT-1283 - $37
GPU - 4870 in Crossfire - $620
Mobo - Asus Rampage Intel X48 - $290
Case - Thermaltake ArmorPlus - $205
PSU - Thermaltake Toughpower 1000W - $330
CPU - Intel Core 2 Quad Q6600 - $200
RAM - G.Skill 4GB DDR2 1000 PC2 8000 - $85
HDD1 - WD Velociraptor 300GB - $300
HDD2 - WD Caviar 1TB - $190
Any Old DVD Burner http://en.wikipedia.org/wiki/DVD_recorder and floppy drive

I'm just looking to see if the 4870 in crossfire would be good, or any other possible combinations or suggestions would be very appreciative and welcome. I'm not partial to ATi or nVidia so go nuts with the suggestions.

I think crossfire is a bit overkill for that resolution, at least 2x 4870. Either 1 4870 or 2x 4850 would make more sense to me.

And for the rest of the setup, you should check the p45 chipset, alot of them got crossfire and are great overclocker for less $. And a 1kW power supply is overkill.

You should be fine with one card short term, it's longer term you'd want to concern yourself with Crossfire.

Right now CF would allow you to raise the AA level without a major hit, and also would keep your minimum FPS pretty solid and high.

I don't think it's worth it to do Crossfire, but there are still benefits.

So based on the chart linked above by runswindows95, If i use the 1680x1050 as a reference then the 9800GX2 would be the best preformer for my resolution?

I personally think that you are spending a lot of money you do not need to spend. Here is what I would change if I were you:

GPU:
Buy a single 4870 for now. Crossfire at 1440x900 is not needed. Some day if you buy a bigger monitor with a higher resolution you can always buy another 4870.

Mobo:
As an owner of an Asus board I can say that I am not fond of them. You seem like the type that may enjoy overclocking and tweaking your computer to get every last ounce of performance. Because of this here is my recommendation for a mobo.

Case:
Nothing against your Thermaltake, but that is one expensive case. Consider this one:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

PSU:
As previously stated 1000 watts is overkill. Consider this Antec TPQ-850. I use it and I have not run into trouble yet. Corsair is also good and they have lots of flavors to suit your needs.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

CPU:
Here is where I would actually spend more money. I would buy a Q9450 if I were in your boat. I just have a soft spot in my heart for 45nm quads.

HDD1:
I do not think a Velociraptor is necessary. They are just too pricey at $1/GB. Heck for less coin you could buy three of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and put them in a RAID 5 array for a performance boost with redundancy.

HDD2: If you need that much space right now then buy the drive otherwise wait. The only direction hard drive prices can go is down.

Well Charz those are my suggestions. Do with them as you please. Either way you will be happy with your computer.

Good Luck,

William

Thanks William, alot of good suggestions. I just need to know should i go with the 9800GX2 or the 4870?
June 28, 2008 2:12:06 AM

I would say 4870..200$ price diffrence

Yep, 4870. While 9800gx2 outperforms a 280gtx, you can always add a second 4870 on that crossfire motherboard for $100 more than 9800gx2. Dual 4870 should outperform it easily enough.
June 28, 2008 2:31:59 AM

Well then for my resolution would i be better off with the 9800GX2 or the 4870 in crossfire. And is the 4870 overkill for my resolution or is the 9800Gx2 better for my monitor.
June 28, 2008 3:07:08 AM

A 4850 is better. Crysis doesn't scale with CF right now.
June 28, 2008 6:50:31 AM

Charz,

I said it before and I will say it again...go for the 4870. One day you may find yourself wanting a bigger monitor. I am on a 19 inch right now and I would love to have the extra real estate of a 28" monitor. You never know what you may want in the future.

A single 4870 is not overkill in my opinion. Think of it this way: You can turn up post-processing like anti-aliasing and get an even cleaner image without a huge drop in FPS that users at a higher resolution would experience with a single card. If some day you want a larger monitor you can always add another 4870. I think the 4870 is just more future-resistant compared to a 4850.

Agreed

The 9800GX2 is overkill for your resolution. CF 4870s is also overkill. WilliamLEJA's suggestions are pretty much all good, though I personally would take a nicer case... I really like my P182 :)

Agreed

The P182 is a very nice case. I was trying to keep it similar to the OP's full-tower case otherwise you can bet I would have recommended the P182. That gun metal exterior is sexy...never thought I would say that about a computer case. I must be easy.

June 28, 2008 12:10:15 PM

Bah! Case... :sarcastic: 

As long as has good airflow, it's all good. $200 for a case! Why not save the money and spending on internal hardware that actually makes a difference in performance?
June 28, 2008 2:23:12 PM

That P182 looks so dull, I just cant do it. I really want a Full Tower and the Armor Plus I really like, the whole removable motherboard tray is what drew me into it.

And I really dont have any internal components to improve on really as far as I can see aside from switching around the GPU, and I may get a Q9450 instead of the Q6600.

I have a Asus P5K-E and am very happy with it. Not sure why your Asus mobo isnt making you happy. Every Asus mobo I have owned have served me well.
June 28, 2008 11:44:02 PM

Major overkill. I'm content on a 8800gs @ that resolution which is far inferior in speeds of just ONE 4870. I haven't yet found a game that isn't complete smoothness except crysis @ very high which would even choke 280gtx.

Buy a better monitor instead and just get a single 4870 if you have money you want to use on your computer. A good monitor can do wonders for image quality and the way you work.
June 28, 2008 11:52:32 PM

Grab just a single HD 4870. Remember, that if you need more power, you can just order another one (and that will probably involve waiting which = price drops anyway) If you find that CF 4870's is overkill, then sending one back is a pain. Better to be on the safe side.

+1 To getting a better monitor if you want to unleash the full potential of the 4870 with or without crossfire. You could get a 24" 1920x1200 monitor for the price of a 4870! CF 4870's on that would be amazing :o

1000W is way way way way way overkill btw. look at this power consumption chart from anandtech.


This is why my high quality Corsair 550 watt is going to last me a very long time, with or without SLI. Stick to a quality 600-watt model (i.e. Corsair, PC Power and Cooling, etc.)

Yes there is amperage and railing details, but it just goes to show you.

Sure I don't want to be running my system at 500-watts all the time, so I'm not going to be SLI'ing GTX 280's under this thing, but anything under even 470-watts should be fine.

This chart actually surprised me, and other charts are similar. Is there something I'm missing?

That is wrong. Those are 12v rail wattage only. The 12v rail wattage output is only a fraction of total wattage output in any psu. Some a higher fraction, some lower. Also, as psu age, output drops. You want the psu to last a while, which means a healthy headroom.

The chart does say.... Total System Power Consumption under Load
I don't know how you figured it was 12v wattage only.
June 29, 2008 12:32:02 AM

And that chart is consistent with what Sapphire recommends for a single 4870 or 4870 Crossfire setup:
–500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)”

I've made alot of changes to my build since the time of my original posting, I'll post it when I'm done making changes.

I know. It's basically the same thing. 12v rail powers cpu, graphics card, and harddrives. In other words, basically everything in a gaming rig. The ampage on other rails mostly go unused. Trust me, 400 watts won't run it.

Trust? Not verify? Sorry, I don't think I can do that.
Although I don't know where you pulled the 400W figure from it's never been just about the wattage or just about the graphics card.
If I was running a modest budget gaming rig (maybe an overclocked E2180 and not that Intel Core 2 Extreme QX9770 rig Anandtech tested) I'd rather run that 4870 with a good 380W PSU with an honest 30Amps of +12v than an iffy 500W PSU with just 24Amps of 12v power.

Feel free to get a 380w psu and find out. Not that the "500w psu with just 24amps," if it exist, will be enough. :na:

So you would choose to power up your computer with a cheap 500watt power supply with low 12volt amps? What about efficiency? :sweat:

Read the reviews, some guy succeeded in blowing up his computer with it. :na: 


NewEgg reviews aren't reliable sources of information. Most put their tech level at high or somewhat hi yet couldn't even tell you whether their PSU had rails let alone what the amperage on them was. And most of them are anonymous N/A people who didn't even buy the item from NewEgg.

The author of exploding PC seems like a tool here noise, smelling smoke, but hey, plug it back in without finding out the source (if there's smoke it's pretty easy to find if you wait unti the smell leaves the area.

Anywhoo just like the bazillion people on these forums complaining about their failed overclocks and BIOS flashes, I wouldn't trust anything someone officially posts on NewEgg as their reason for trying to return it and their review to bolster those types of claims. :pfff: 

I'm not pro OEM, I'm simply anti New Egg reviewers.
