Which card to get? 4850-4870

Hey everyone! I need a little help selecting a video card. I am stuck between getting an HD 4850 or an HD 4870.
I don't know if I should get the 1gb version or 512mb version of either card. I am currently looking at 2 different 4870s. Here are the ones I'm looking at:

HIS Hightech H487F512P Radeon HD 4870 512MB

ASUS EAH4870/HTDI/1G Radeon HD 4870 1GB

There is also a Sapphire version of the 512 for a little bit less. The monitor I am planning on buying is 1080p

I am trying to keep my entire build under $1000, and right now it comes out to $1107 with the 1gb 4870. If it is worth the extra money I am willing to pay for it, but don't want to go any higher. Would it be better to go with a less expensive monitor and a 4870 or 4850? Thank you for your time!

Thanks for the reply!
I want everything to look as good as possible for a while since I probably won't upgrade anything for about a year. If that's the case should I go with the 4870 512, or just go with a 4850? Also, what would be the better choice for that monitor?

get what you can afford. If you can get the 4870 1G and still eat, then get it. If you plan on playing that monitor at 1900 with high settings, you may need the 1G. But 512M will work just fine at 1200 to 1600. Well, Far Cry 2 and games like it may need more.

I have had real bad experience with sapphire. They have ok cards, but the customer service is the worst i have ever experienced. I had a card go bad at 35 days in. I emailed, called, etc, for 5 weeks. They never contacted me with an RMA. Google sapphire customer service.

What are the rest of your specs?

on another note: Toms is different. How do i select my sig?

Heya,

Look at the actual differences hardware wise between the 4850 and 4870.

In other words, get the 4850. Overclock it yourself for free.

Personally, I like the 1gig versions of cards because I like to max out textures and resolution and turn on AA when possible without killing performance. I've read reviews that claim the 512 vs 1gig doesn't do much difference, but if the difference is 25 fps without and 30 with it, I'm going for that 30. I just want it to be smooth and beautiful at max everything when possible.

Cheers,

+1 for 1gb 4870...

+1 1gb 4870. Yes it is questionable whether 1gb really gives you that uch more improvement over 512mb but IMO, with games like Crysis and Farcry 2 requiring that extra boost for things like AA it is surely the case that the number of games requiring this will increase. So in the long run you are saving yourself some cash.

Craxbax - why would 1gb of memory hamper ocing headroom?
