Confused on Upgrading

[THE_SITUATION]

to cut a long story short im not sure what i could upgrade to gain a performance increase in games i do however know a new monitor is needed as mines a 22" lg lcd with huge blurring issues in mmorpg's.

my setup

crosshair V forumla
amd 1100t 3.3ghz / cosair a50 cooler
8gb gskill 1333mhz
corsair 850w hs psu
sapphire hd 6870 1gb
seagate 1tb sata3

so first off ive done research and with mmorpg's as loading more players on the screen its said an SSD would help?

monitor im looking for a 24" doesnt have to include speakers as i use in ear headphones but good response time would be nice.

ram, now ive had a look on the forums and (upgrading to 1600mhz wouldnt give a significant performance increase?) however tighter timings such as gskill blue edition would perform better correct me if im wrong ?
bare in mind as im running an amd board the height of the ram is an issue so corsair vengeance is out of the question unless it was low profile.

seriously any help is welcome as im struggling on what could help me in gaining a performance increase

 

[THE_SITUATION]

I am connected through ethernet and it all seems fine on that point as i get average 30-50ms on the server, the ISP is o2.

world of warcraft is the mmo that im currently playing but with poor performance it is very hard to stick around on it as that game seems to hate amd.

resolution wise im running 1680x1050 as previously said its quite an old monitor

crossfiring isnt supported im afraid

i did do some tests and i believe the problem could be the monitor, when im running around or turning everything seems very blurry and sharp making it seems like poor performance but i do have 20-30 fps on a crowded server in a very populated area. could a bad monitor really be the problem ?
