Your current GPU might be fine (honestly, I know very little about GPU's since I'm not a PC gamer), but Maximum PC recently did a benchmark on top GPU's and the Sapphire R9 290X Tri-X clearly came out on top. I've always opted for integrated GPU because I don't do anything with graphics. This is just food for thought, I'll let others take it from there.
I do know about SSD's though. Do NOT buy a SSD that uses asynchronous NAND. As far as I know, Kingston and PNY are the only two companies currently using that. I recommend Crucial personally, since they have very reasonable prices.
I don't like AMD's line of GPUs given the bad experiences I've had with them in the past, same goes with their CPUs, same deal, I've had one of them fry on me before. Intel+nVidia all the way
That being said, I don't need anything super high-end, 200-300 dollars is a good range for me to focus
I dunno why I mentioned CPU update, mostly because some games, like AC: Unity, my CPU doesn't even meet the minimum specs, yeah, the game is that piss porr in optimization.
So many responses from you guys, thank you
Qtis SSD is still quite a ways off, I currently have two HDDs in my case, both Western Digital 1 TB drives at 7200 RPM, would an SSD still be the way to go for an OS partition? I'm still on the fence, but SSDs don't even take up power at all, and I do have a 2.5" drive bay, so I can fit one.
Sicklyboy How good is your rig for Dolphin, PCSX2, etc? Do games like The Last Story still struggle even with the improvements the emulator has seen this year so far? I don't know why I suggested CPU upgrade since, well, the differential would be negligible, right?
^ This.
8 GB of RAM should be enough for anything unless you are a heavier multitasker than I am. Your PSU should be powerful enough to not need upgrading.
If you want, you can get an aftermarket cooler and OC your CPU. That's not something you need to do at this point though, but eventually when you find out that the CPU isn't powerful enough anymore, it will get you a good few more years of use out of it without costing you much.
I still use a Core i7 920 but I overclocked it to 3.8ghz from the stock 2.66. I recently upgraded my GPU to a GTX 970 so my PC should be powerful enough to run pretty much anything and I don't see myself needing to upgrade it again for a long time.
Actually, if you look at the OP, my CPU is the 3750 non-K version, so because of that, I can't overclock. I got the non-K version because I never had the intent to do so. Judging from the posts, it sounds like that GPU is the best thing to upgrade, given the general consensus of the thread thus far.
Sorry for not quoting everyone's post, I don't want to clog the thread with a huge post, you know, so far, I'll keep my eye on sales for GPUs as 300-330 dollars might be, well, a tad steep. I never have, nor will I ever overclock since it cuts the lifespan and voids the warranty.
