What graphics card?

I've heard there are some driver issues with the 4850x2. I'd lean more towards a 4870x2, they have come down in price and most have a $50 rebate. Another route would be to get a single 4870 now and then go crossfire later. You should also check out the combo specials on newegg, they have some great deals for P2's with mobos and video cards.

What resolution are you using? Is your PSU upto running 4850x2?

oh sorry i have an 750watt kingwin power supply that a just bought last month
im running on 1920×1080
thankyou

That is a Tier 5 PSU. How much did you pay? You may need a better qulity one for 4850x2

i have a kingwin mach1 750watt ps not the most efficient or quite power supply but i think it is a good performer

i could have got something better for the price ($155.00). but it had fit the look of my rig and it fits all my needs

Perfect example of a way better PSU for the money. I've seen Kingwin PSU's go up in smoke in less than six months. If you're going to rebuild, I highly suggest getting a more reliable brand of PSU, at least something from the Tier 2. A tier 5 psu means it's something HP puts in their machines and I've seen a Kingwin take out a system in less than six months.

it's not like it's a $50 powersupply. i have no concern of it failing and im not worried about it. all of the mach1 series power supplys have good rating on review sites and newegg. im not saying its the best. but im not gonna throw out a new $160 investment that has no problems to spend another $160 on a "tier one" powersupply.

so back to my question

im think im going to go with the 4850x2 2gb i am aware of sapphires driver issues but the issues may have been fixed. it seems like the most logical choice right now in this price rage

does anyone know why only sapphire is making the 4850x2

do you guys think the 2gb card is worth the $35 over the 1gb. im thinking 512mb/per card is a little low for high resolutions

i dont think that you can say this power supply is as bad as a power supply from hp. i think this guide is false about the kingwin power supply, there probably just taking the real cheap kingwin power supply's into account

anyway's what the f*** does this guy making this list know about power supply's and how does he come up with it.

Since your 680i board supports triple SLi you should think about going with a 260 sp 216. Even though the 4850X2 is faster you will generally be limited by your CPU. Adding another 260 sp216 latter will give you more performance than a single 4850X2 and since that board doesn't support crossfire you wouldn't be able to add another 4850X2 either.

If you don't know how its done, why claim that he's wrong? Believe it or not, there might be people out there that know more then you.

I'm going to vote with a 4870 1GB/GTX260 216. Get whichever fits your budget or "rig" better. Either of these will handle 19x10 ok, and you can carry it over once you ditch that horrible P4D.

good points megamanx, I didnt realize the board didnt support crossfire. The 4850x2 doesnt really have a big market as most people would opt for either a single 4870 or a 4870x2 unless they went nvidia.

well the board will be replaced when i upgrade my system in march so i may get a crossfire board and im not worried about my cpu limiting graphics card because i will be upgrading.

im thinking more about the gtx260 216, im hoping the 4850x2 will goes back down to 300 because i would buy that.

I just dont feel like the 4850x2 is worth $300. If I were you I'd get a single 4870 now and when you upgrade your mobo pick up another 4870. Or if you have the money now, just go for a 4870x2.

yeah if i can remember the 4870 can beats the gtx260 216. i think my finale choice is the 4870.

A 4870 is equal to 4850cf or 4850x2:

4870 1G for $250:

Plus arent the 4850x2's longer. The 4870 might fit better.

4870 1G has equal performance, lower price and will fit better. Get a 4870 1G.

compared to a GTX 260 216 it is a toss up. If you stick with a nvidia board, go with the GTX 260 216 if you go with an intel board go with the 4870. Only because of SLI or Xfire compatibility.

What are you going to be upgrading to?

You will never, ever get good advice on a GPU untill you provide the specs of your display. What size and resolution do you run at? Do you like to use AA ect? Do you game ect?

He said 24" so its 1920 x 1080
