Most newer games' minimum requirement is set at GTX1060 and above.

Though since your CPU is kind of outdated and will bottleneck anything as powerful as 1060 and beyond, I'll suggest you to go with basic low/mid setting card like 1050TI.

Though one warning, current pricings for GPU (even those cheapo entry cards) are too ridiculous to be worth buying, even those 2nd hand or old mining cards. If you happen to find one 1050TI around, it will likely cost more than RM650, and it's hell not worth for the price (at most I'll pay RM550 for it, and that's IF I'm despo).

It’s nowhere here or there.

I’m not too sure if your z68 mobo supporting i7 3770 (the last pinnacle of 1155 socket), but even doing so it’s not gonna be overwhelming improvement either.

Just grab a “reasonably priced” GTX1050TI or GTX1060 and call it a day, live within what your 2500k can push for; save whatever extra for future. Just FYI nowadays, 2nd hand 1050TI around RM700; 2nd hand 1060 3GB around RM800 and 2nd hand 1060 6GB around RM1k+; all are quite ridiculously high for 6+ years out of warranty legacy cards…

A proper system upgrades will cost several times more than what you budgeted, let’s keep them for other years.

p/s: just noticed that your RAM is kind of limited (and single stick?), consider adding another 8GB stick to it, won’t cost too much extra. Also your SSD is likely quite full already so can consider some slight upgrade there too. 2.5” SATA3 drive will do as your mobo don’t have proper NVME M.2 support.

Nope, your mobo don’t support DDR4. Just go garage sale and grab another stick of 8GB DDR3 will do, they don’t cost too much nowadays.

As for SSD, since your mobo don’t have NVME m.2 SSD support, just grab a typical 2.5” SATA SSD will do. As more model, just grab one with DRAM cache and 3D NAND. That’s the balance between performance, durability and pricing. For model you can look for Curcial MX500, ADATA SU800, WD Blue or pretty much any Samsung. The price you’re looking is bout RM180 for 240GB drive, with 480GB drive costing bout another RM100-150 on top of that.

Don’t bother running old card in crossfire/SLI, especially since it only have 2GB RAM.
