I'm very new to PC gaming and I really don't know about graphic cards.
I look towards buying the msi GTX 750Ti Twin Frozr OC Cards, which I will be using the i3 core processor.My PC is Asus K3a0d. I want to play games like Battlefield 3/4 and titanfall. Should I buy this graphic card? Will it support my PC?
A web search for Asus K3a0d does not find anything (except this post....) We'd need to know more about the specification of your PC - mother board etc. If your PC will support it - and it probably will - the GTX 750Ti is a decent mid-range card, but I don't think the combination of an i3 and the 750 will enable you to play those games at maximum settings. It'll probably do a pretty good job at moderate/high settings though.
Ive seen many gamers that use i3 processors about 3.0gHZ, its pretty decent, but in matter fact I'm on a low budget. Ive seen gamers playing games like titanfall with gtx's on i3 processors. But I'll give it a go. But the graphic card may be convenient for the gaming though...
From the Asus web site this computer will only have a 350W PSU the recommended PSU for this graphics card is 400 W and with only 4GB ram I think you will be disappointed. You would also need to know if there is enough room for the graphics card.
agree with wee eddie i5 bare minimum for modern games a lot will throw i7 as requirement. currently running i5 @2.8ghz with boost to 3.5 ghz but that only gives me mid range with gtx 770 with the newest titles granted board slows it a bit as only pcie 2 and card pcie 3 but would seriously have a rethink on your spec even for mid range offerings
