hey guys,
i need help on this one...am building a new gaming rig..and i would like to know which option is more powerful on a 22'' samsung full HD display:
2x 9800GTX+ 512 DDR3 (i already have one so this option gna costs 200$ ONLY!)


Or


2x Sapphire HD4870 2GB vapor-X edition(gna cost 600$)
which is equal to 4 gbs or ram..{ASUS MARS(L)(L)}


btw am gna install a 800W coolermaster powersupply
reply plz
 
get another GTX and slap it on your mobo, save yourself some cash and a free headache.... if you had a bigger monitor with a larger resolution then dual 4870's would make more sense..... dual 4870's would be overkill for a 22" screen.....

Two 4870's will outperform two 9800GTX+'s, however, for the price savings it really isn't cost effective to make the jump to two 4870's when you already have a 9800GTX+. I have to agree with Obsidian86 as well. If you are going to spend $600, don't waste the money on two 4870's when you could have a 5970 for about the same price. Personally I would just add a second 9800GTX+ though.
 
Video card performance and monitor size/resolution CANNOT be matched up - you play doom 3 these days on any basic card and at max settings at whatever res it will work, not so with any modern game.

You want as much video performance as you can get aslong as its within your budget, if you can afford better, get better.
 


what??? that makes no sense whatsoever....

first of all I doubt the OP is thinking of dual 4870's to play a game of Doom 3 or equivalent. The resolution has EVERYTHING to do now at days when it comes to GPU sellection. Since the OP already said he would be using a 22" screen it is obvious that dual 4870's would be overkill UNLESS he is aiming at full xAA with smooth frames. He already has a GTX so the best choice would be another GTX for SLI...

not to spoil obsidians post but a 5970 would be MAJOR overkill.... :ouch:

His 22" full hd screen has a resolution of 1920x1080 which is the important part, not the physical screen size.

A single 512MB 9800GTX+ is essentially a GTS 250. Two GTS 250 are roughly equal to a GTX 285. A single GTS 250 is equal roughly to an HD 4850.

Two HD 4870 are roughly equal to an HD 4870X2 which is roughly equal to an HD 5870. Do not pay for a 2GB version; 1GB is enough.

The two HD 4870 are going to easily outperform the 9800GTX+ SLi, but if it were me I'd just a buy a single HD 5870. Chances are it'll be in the middle of adding another 9800GTX and buying two 4870s. A 5970 would be major overkill, but anything at or up to an HD 5870 is fine at 1080p.

Just because there are other options available given your m/b slots , money , configuration does not mean it makes any sense to do so. We don't know if you want to spend 300 PLUS for a 285 and relegate your fairly strong GTX to daughter board status. That does not make much sense. Go sli with what you have and wait for the next gen of NVdia cards to see how the GPU landscape looks then.

Two 9800GTX+ will not net anything too amazing in Crysis at Very High; it will probably give you around 25-30 frames without anti-aliasing. Other than that and S.T.A.L.K.E.R. you should be fine though. Also, your resolution is not really full hd, the maximum high definition standard it supports is 1280x720 which is 720p, not 1080p which is 1920x1080 since you seem to be running at 1680x1080.

What currency are you paying in? Hopefully not USD, because that's really high. Remember a 9800GTX+ is just a GTS 250 that uses more power, so two 9800GTX+ roughly equal a GTX 285; there's no reason to buy a single one when you can pay less and just add a 9800GTX+. Buying a GTX 285 and using the 9800GTX+ as a PhysX card is also a waste of money because it doesn't really offer you anything. Even if you're playing Batman it comes at a performance hit on high (which is required to actually see a difference), not to mention there's virtually no other games that anyone cares about to use it.

Just add another 9800GTX+ and wait for prices to drop on ATi's five series and see what Nvidia has to offer sometime this decade.

well unfortunately i pay in dollars my friends...but my fellow lebanese people here dont even know what a real gaming rig is...the 4890x2 costs 660$(including VAT)...so most probably the 5850 gona cost more than 800$ here...most of the dealers here are robbers i hate tech shops here...i called they ASUS official distributors here..they havent heard abt the rampage II gene yet!:S its sad to know that most people around you are non-educated wanabe's
