Gaming PC rig

[DipMaster]

OK, So after months of trying to solve why my 750ti 2gb cant play games like killing floor or dead island at 1920x1080 at lowest settings with v-syn off without stuttering or mouse lag, I have decided to maybe upgrade it to a 970 or a r290x 8gb, just wondering if the other parts from this rig would be able to support them sufficiently?
i5-4460
gigabyte z68-d3-b3
(with the ram I have 2x4gb 1333 from an old built and 1x8gb 1600 from this built I could use them both for 16gb?)
I have a sata HDD and dvd drive, and a stock cpu fan, along with a zalman z9 case, and a stayqiet 530w psu. any help much appreciated had lots of problems with the old pc just dont want to spend £100's on new parts to have the same problems

also could someone help me out with what gpu to buy? I was thinking 970 or r290x but there are so many with such varied prices some help with that on whats best for value for money (the 8gb cards sound interesting) would be appreciated too thanks

Ummm... something is wrong here. How do you have an i5-4460 (which has a LGA 1150 socket) coupled into a motherboard that uses a LGA 1155 socket.

The i5-4460 should not be working properly on a Z68 motherboard, the sockets are different.

ah, well im currently using a GA-H81M-DS2V that came with this prebuilt, the z68 is from an old custom build, would the h81m work with a much bigger card?

<3 adtr btw 😛

Lol good to see somebody who knows them, and as for the h81m, yes, it should work much better.

right now im running a 750ti with 8gb ddr 1600 on the h81m with a 600w corsair psu, and I cant even play KF2 without mouse lag and screen tearing (or kf1 for that matter, flawlessly anyway everything on lowest possible settings apart from being 1920x1080 res) i cant help but feel that a 750ti 2gb sc should be able to run either killing floor game on lowest settings at 60fps flawlessly, i feel like something is bottle necking it

 

[DipMaster]

and know them? I eat shit and breathe adtr xD

I have the 750ti as well, and it definitely runs Killing Floor on more than low. There may be something wrong with the card, if you're constantly getting bad frames. But first, have you run disk check, virus scans, etc?
