GTA 4 with HD3870X2

Hi!
I've been playing GTA4 and noticed that all settings aren't at the highest, you probably guest it - Texture Quality.
The ATI HD3870X2 is a card that uses 2 GPUs without needing a CrossFire Support.
My computer does have CrossFire support.
When I was buying this Graphics Card I bought it just because it's price - 2 of HD3870 would cost 400$ but this HD3870X2 cost only 260$.
I'm thinking to add another HD3870X2 and use it with CrossFire (2 GPUs x 2 GPUs = 4 GPUs ; max 4 GPUs) and I can't add any more cards, right? (I have 4 slots).
Will I be able to add this setting to High with the new setup?
- High requires 600MB of memory
- I will change the resolution from 1680x1050 to 1920x1080, new monitor.

If this is a bad setup and I won't be able to play GTA 4 at highest settings, then what card I should get(ATI) ?

i hear for gta4 its more about you cpu and less about your video card

i have a q6600 and a 8800GTS (G80)640mb
the game runs great, everything is maxed but for the texture quality

What kind of a bug it could be?
And any proof about that it will be possible to play with highest settings?
Can't imagine what kind of a mistake they made...

And back to the topic about adding another card?
I understand that memory won't just get bigger.
Is micro-stuttering very noticable in this kind of a setup?

Also I have a good CPU and I'm able to play GTA4 without any lags, just without High texture quality and I think I should be able to play this game with all the highest settings just without any restrictions.

Isn't good performance at high resolution starting from high memory clock? (Sry, I don't know, just making sure).
Any reports about playing GTA4 at 1080p with this card?

Monitors and High Resolution Gaming.
Ultra High resolution gaming is entirely possible, and exactly the reason you should be considering a multi-GPU system. Therefore it is essential that you consider your monitor, particlularly in the case of TFT's. Bare in mind that you really will not see the benifit of a SLI rig at this level running at anything less than 1600x1200, due to CPU limitation, and really the only advantage would be higher benchmark scores. All that power will just not be used on a 17" TFT with 1280x1024 native res, and i would consider a resolution of 1024x768 a complete waste!!!
Basically, if you arent bothered about benchmarks, and can only run at a resolution no higher than 1280x1024, dont expect to be 'blown away'. Maybe consider a monitor upgrade and a single card in the short term, you can always add a second card down the line. Multi-GPU setups, including crossfire, and designed to be run at high resolutions, high detail settings, with AA and AF applied. Afterall, thats what you pay all that money for!

Btw, the new monitor that I'm looking forward in buying is BENQ E2400HD (24", 1920x1080 with HDMI)

gta IV is broken, i doubt adding another hd 3870x2 will solve the problem, rockstar has to release a patch to fix it

getting the monitor would be good though, the 3870x2 by itself can run games that are not broken at 1920x1080 pretty well

I'm not upgrading just for GTA4, I want to add another card for a later game, because I can do that now and not later. Actually wanted to hear someone's opinion that has these 2 cards togheter. And im worried about the high resolution - maybe R* fixes the texture problem, but maybe there isn't anything to fix for high resolutions.

Ok, I will see how games work with that resolution.
As for adding another card im worried about micro-stuttering and probably won't upgrade because of it. I would like to go to a newer card like the 4870X2, but I kinda wanna keep the old card, maybe there is a way 4870(not X2) + 3870X2?

I don't see actually why could 4870X2 be better then CF 2X 4870, or simply a single 4870(if memory doesn't doulbe up) or is it the same?
So lets see how the new monitor will act, maybe there is soneome who bought this monitor and could give a good word about it?
But it should be good at the end anyway, otherwises I'm buying a new 4870X2 and giving this one to a friend that doesn't have a CF enabled MB and works with video editing(FullHD films).
Oh, btw, maybe somone knows a good, cheap card for video editing (Pinnacle Studio), 3850 256MB is too slow.

gta 4 really wants quad core for the best performance

Q9650 3Ghz 12Mb L2 Cache.
2 * 2 Go DDR2 PC6400 Dual-Channel
F**KING ASUS GTX 295

Nothing to do, i tried to launch "launchgtaiv.exe" -nomemrestricts -norestrictions

Nuffing to do =(

Hope Rockstar will Rock again soon !
