Just bought a new gen graphic card Asus R9 270x, my computer is kinda old,

My question is how much is my old computer bottlenecking the new GPU card? Did i buy a Graphic card that is too fast? I can run everythink on ultra quality in Battlefield 3-4 but then i tried GTA 4 and the FPS improvement from my old Radeon 7770 HD isn't that great considering i had quality almost maxed out before already... I know GTA 4 has terrible frame rates but i was expecting much bigger improvement from the 7770 Radeon i had previously.


here are the exact specs:

CPU: Intel Core2 Quad CPU Q6600 @ 2.40GHz
Motherboard: Gigabyte EP35-DS4
RAM: 2x 2GB 400Mhz(Dual channel) 1x 2GB 800Mhz
GPU: ATI R9 270x
PSU: Corsair Gaming Series™ GS800 — 80 PLUS 800 Watts
Hard Drive: Toshiba 7200 RPM performance, 6 Gb/s SATA Interface

Well, theoreticly, the CPU is kinda old. Upgrade would be needed. How much FPS increase are you getting? Overall i mean. + is the memory DDR2 or DDR3? Your motherboard might not have PCIE 3.0, wich the 270x makes use of.

I think both are helping their fair share with bottlenecking as both ram and cpu aren't the newest. Your cpu can handle it pretty well, but your ram card seem to be too outdated. You at least want ram cards with at least 1066mhz and 8 gb of total ddr3 ram. Not having those is the biggest bottleneck in your system.

well, i checked,a dn your MOBO has ddr2 ram, you cant upgrade to DDr3 unless you buy a new MOBO aswell. Thats means a new CPU aswell. IMHO, you should buy a new system , except the R9 270x that you have already bought. THEN you would see a difference : )

The problem with RAM is that it is DDR2, and i'm fine with the CPU for now but i'm not willing to spend money on DDR2 ram, especially cause the Mhz limit for DDR2 is at 800Mhz, will buy new CPU + mobo + RAM soon, went with GPU first cause it's compatiblle with any mobo.

GTA IV is pretty CPU heavy too, i used to get terrible framerates on a 7970Ghz edition, just because i used a FX6100 CPU! So it's defently the CPU which is the bottleneck here. Though upgrading the CPU also means upgrading the motherboard & ram, so it's a mid-sized upgrade of your pc. :) 

I would get the FX6300, FX8320 or the i5-4440 for this pc, if you're thinking about the upgrade possibility, the latter options i listed are the best, and the middle one if probably going to be the best bang for your buck. That plus a decent motherboard and 8GB of 1600mhz ram. :)

GTA 4 is badly optimized anyways..

30fps when in high speed on my overclocked i5-4670K & ASUS R9 290, totally agree.

i5 4570 and my old hd4850 was getting 50, so yeah, it's REALLY badly optimized.

Well i forgot to mention that Battlefield on Ultra 1680 x 1050 goes smooth 90-120fps during first mission, unfortunately most games aren't as optimized as Battlefield.
