Swap graphics card?

[Dene76]

Hi all,

My new[ish] rig from PCS [3 mths old], runs Flight Simulator [9 & X] ridiculously good.
However, in FS9 the anti-aliasing does not work and I'm told this is due to my graphics cards, 1GB NVIDIA GEFORCE GTX460, in my current rig can I simply replace this with a 1GB ATI Radeon HD5770?

My full specs are below:

Processor (CPU)
AMD PHENOM II X6 1090T (3.20GHz/9MB CACHE/AM3/125W) - BLACK EDITION
Motherboard
ASUS® M4N98TD EVO: DDR3, 2-Way SLI, SATA 3.0GB/s
Memory (RAM)
8GB SAMSUNG DDR3 DUAL-DDR3 1333MHz (4 X 2GB)
Graphics Card
1GB NVIDIA GEFORCE GTX460 GDDR5 PCI EXPRESS - DirectX® 11
Memory - 1st Hard Disk
Change to: 640GB SERIAL ATA 3-Gb/s HARD DRIVE WITH 16MB CACHE (7,200rpm)
Power Supply
CORSAIR 650W TX SERIES (TX650) 80+ ULTRA QUIET PSUOperating System
Operating System
Genuine Windows 7 Home Premium 64 Bit - inc DVD & Licence

Thanks in advance!

Going from the 460 to a 5770 would be a serious downgrade.

I agree - I wouldn't change the graphics card. If you wish to go down the ATI route I would recommend the 6xxx series, perhaps a 6870?
