5770 or 5850

I have two scenarios in my mind now..

2 x 5770 + 890FX Mobo ( more expensive power supply added into account + other factors if any )

OR

1 x 5850 + 890GX Mobo ( cheaper power supply theoretically and the ability to later crossfire. another question here... will the 8x/8x configuration bottleneck the gpus if i did crossfire on the 890gx mobo? )

The processor i intend to install is 955 BE but im considering the 1050T also but articles on toms indicate its not much of an improvement... also the bulldozer cpus are coming out next year so it might be wise to just install the cheaper 955BE for now.. any other opinion on that?



So now three questions total... the cpu... the gpu config and the 8x/8x question

Thanks!

P.S. i live in middle east so no online websites....
but i did refer to the prices on newegg, toms articles and passmark.com

Assuming this is a gaming build.
1. Yes use 955. Hexacore useless for gaming.
2. 5850 is better idea as it doesn't max out your PC right off the bat.
3. No x8 lanes is not an issue. Only time it is is when you want to use more than 2 GPU's.

My personal preference when building a system is to leave room to upgrade if you intend to, whether you ultimately end up needing it or not.

8x/8x isn't going to significantly affect your experience, you are fine going with that setup. The most commonly stated figure is that it can affect performance by about 4-5%, but that is with 5970s.

I'd suggest going with the 5850+890GX, but get the more expensive power supply now (if you can).

If you're just planning on gaming, get the 955 BE now, and if you end up needing more processing power, get bulldozer next year. It's unlikely that games are going to start using 6 cores any time soon, and the higher clock speed of the 955 will help out more with current computing tasks.

thanks guys.... now any recommendations for a 890 gx mobo? looked at asus gigabyte and msi.... any brand preference that i should have or somethin?

My pc would look something like this i guess

CPU : 955 BE
PCU : 650 Watts ( not sure which one as yet but hope 650 watts is enough )
RAM : 2-4 GB DDR3
GPU : 5850
MOBO : 890 GX chipset not sure which model

Havent decided casing, drives and hard disk

I went with a 5770 for my build to save money. Debated heavily on the 5850. I have just picked up a second 5770. I really, really wish I had gone with a 5850 in the first place. Now I have $325 in graphics cards that I would probably get $200 on ebay for. I strongly recommend the 5850.

And yes its a gaming pc.... is it important to shell out more money on cooling and stuff? coz i dont i would have any left :o

650W will be enough, ATI recommends 600W for 2x 5850. As long as you're not overclocking and running 2x 5850, you'll be fine.

As long as you get a case with decent airflow (say, more than 1 or 2 fans), cooling shouldn't be a problem with stock. You don't need to buy a CPU cooler if you don't overclock. If you do plan on overclocking, then you will want to get an aftermarket cooler, but you could also wait on buying that if you're not going to overclock right away.

As far as 890GX motherboards, I'd see if you can find one of the following:
MSI 890GXM-G65
GIGABYTE GA-890GPA-UD3H
ASUS M4A89GTD PRO/USB3

All three of these boards are within $10 US of each other, share pretty much the same features, and are made by quality manufacturers.

x2 I'm in the exact same boat. I was digging the idea of having a xfire setup coming from 2 7800gt's in SLI (my last pc was that old) but after a few weeks, I'm thinking that getting a 5850 back when I first built the new rig was the way to go. It'll run everything out now at near all high settings, and xfiring it later down the road should be a vast improvement. Now I'm stuck with 2 5770s that will be obsolete by xmas maybe....
