Question about graphics cards and my system

[blacktiger]

Hi kinda of new to forum and would like to ask a question to the pros as im not very tech minded and maybe save me a few £s

Ive got a system near 5 years old now, its a

asus p6t deluxe v2 system
i7 920 oc 2.6 - 3.4ghz
12 gb ram
900w tagen psu
and at present using a geforce 295 gtx
running vista 64

my question is, as being a battlefield fan im wondering if i could just buy a new gfx card maybe a r9 290x, a gtx titan or a gtx 780 gpu upgrade to upgrade my system to be able to play it with decent graphics or would i suffer due to the system i have and have problems

i am prepared to get a new build but woulda like to clear this up first

thx bt
