Default Going from 3870's to 4870('s)?

I'm debating on ditching my 3870 tri-fire setup and ugrading. I'd like some advice from others who already took the plunge. Since I have a crossfire mobo I'd like to stick with ATI for future upgrading possibilities, obviously.

Here are my questions......

1. Would I gain anything going from 3 x 3870 gpus to 1 4870?

2. If so should I get a 512mb or 1gb card? I've read a few reviews about this and the answer is unclear. I have a 22" monitor BTW.

3. Would it be worth it to go all out and get a 4870X2, or is it a waste of money @ 1680x1050?

Thanks guys.

1) not sure haven't seen a review of that
2) 512 mb card
3) It is an awesome card and is cheaper then dual 4870's Although you would see bottle necks with your cpu. The 4870 should be more then enough.

Well I just tried my buddies GTX260 core 216..... what a beast!
3DMark06 and Vantage scores are a tad lower then my tri-fire, but playing Crysis Warhead was alot smoother at similar fps. At 1680x1050 on all enthusiast with no AA, the frame rate average was around 30ish and stayed above 20 on the beach in the "Call me Ishmeal" level. Very playable! It was wild.

I'm thinking I'll go for a 4870 and 9950 Phenom.

I bet you'll have fun with the 4870, but it's hard to say whether the phenom will yield any improvements. You've got a solid overclock on your present chip, and it's still rather hard to find common applications that will be able to use those two extra cores, much less any games that can.

He's right killswitch resist the urge to get a 9950.

The only time I would upgrade my cpu to a phenom is if the 9850 was $100 thats why you still see me with a dual core.

Agreed, spend the extra cash to get a 4870x2 ;)

Or for a compromise, the 1GB 4870's are showing their faces now, and that extra memory could represent a fair amount of future-proofing, for only a little more cost.

You do have a nice overclock. I only said if you bought the 4870 X2 you would see bottlenecks but a single 4870 you wont.

For a 22inch monitor a 512 4870 is fine, overclocked it will be amazing. Its still a good $50 more for that extra 512mb. Yes it will give you a bit more future proofing but by the time that happens there will be much more powerful cards-theres only so much the 4870 architecture can do.

Also I'm not sure what to make of the Anatech review as it looked like they just copied and pasted the results they got with the 4870 back in June (factory drivers)..the 512 is a few fps faster now with newer drivers which would put it level with the 1gb at anything other than extreme resolutions or massive aa in crysis-more in line with another review of the 1gb vs 512. Sky really needs to get one and do a review as I dont trust most of the reviews on the web.

Due to Far Cry 2 supposedly being able to make better use of multiple cores, that is what's fueling that thought.

Furthermore, games like Crysis (and likely Far Cry 2 aswell) have tons to render.... even at 1680x1050. So I think an OC'd 4870 with 1Gb of ram would be better then the 512mb version there.......... but in other games? Definitely not so much as mentioned.

My brain hurts now. :help:
