Right now I've got:
Win7 Ult64
5GB ram
2.66ghz intel quad core
NVIDIA geforce 9400gt

The game is smooth at next to best graphics, but it gets very choppy when I turn it all the way up, but it looks so nice, I wanna be able to play that way. What suggestions would you make?

5770 for $170 range

or

5850 for $275 range

Thank you :-)

are those nvidia cards? ati? The numbers themselves don't tell me enough to find a product online.

==============================


Nasty "lag" when menus are up
Chunky feel to the ground game.

Other than that usually smooth as silk.

I get 60-90FPS with CoD4 on max

Graphfics Card: EVGA Nvidia Geforce 9800 (I have SSC but they are really hard to go so get the GTX). THe 200 nvidia seres are going down in price pretty quickly and just one will run fast, quite, and cool. Good luck shopping around.

THe rest of my setup is below. Game runs awesome on 1920x1200 max settings 120hz refresh hdmi hookup.
EVGA Motherboard 780i SLI
Intel 3.16 Core Duo
1333 front side bus
Windows Vista 64 bit Home Premium
8 gigs ram (only need 4) - fastest ddr 2 ram with 1333 front side bus spec

I'm surprised you get anything near "smooth" with that card, even on the lowest settings. Even with my 4830 I wouldn't call the gameplay smooth (on ground based missions).

That said, the best card on the market currently is the 5890... but I'd go with a 57xx , best for a budget gaming card. It'll get you through almost any game for a year or so.

ATI Radeon Asus HD 5870 1 G ...Graphics cranked, no sputters. Expensive a tad, but good for a while to come.

Cirrus Logic GD5000 series FTW!!! can get half a meg, or even a full meg!!

i5 650 pumped to 3.75ghz on air
Gigabyte GA-P55-UD4P
4 gigs of ocz ddr3-1600
Radeon HD 5770

Game is on max settings with full on AA (8x I think)

Smooth 98% of the time I think the remaining 2% is server related

9800 would be much improved
