Updating my video card but have a few questions

[Lonefox]

Hi guys, im thinking of upgrading my rig a little, specifically the video card. My current set up is:

E6600
G.Skill 2gb DDR2 800 (HZ)
HIS ATI 1900 ICEQ 3
antec truepower2 (550w)
Gigabyte 965p DS4 mobo

Now im aiming to play something like fallout3 on some high settings at 1680*1050 and im looking at this card to do the buisness:

http://www.overclockers.co.uk/showp...5 TV-Out/Dual DVI/HDMI (PCI-Express) - Retail

I have a few questions however, this card says pci-e 2.0 support however my mobo is only pci-e 1.0a i believe, will it even be compatible and if so will it be at a slower setting?

Secondly will anything in my system seriously bottle neck this card? or would it be wise to save more pennys and do a full mobo/cpu/ram/video update?

Any help appreciated!
Si.

Thanks for the replys looks like ill just be getting the card and possibly some more ram, I only have 32bit vista and i've heard it will not support that amount, is that true or just lies?

Also can someone recomend me some RAM? i do have 2gb og G.skill ddr 800 (HZ) but OC doesnt seem to stock these anymore so i can't just get another 2gb of that :S

time bomb capacitors? O_O

Thanks again, can someone recomend me some RAM then? i currently have:

2x G.Skill PC2-6400 (400mhz) F2-6400PHU1-1GBHZ (4-4-4-12)

OcUK doesn't appear to stock these anymore so i cant just get two more of them, im assuming it might be best to get a new 2x2GB kit, if thats the case could you recomend me one please?

my mobo "Supports DDR2 800/667/533 memory "

Cheers,
Si.
