New CPU or GPU

First off sorry if posted in wrong section.

So, recently I found out that my wife is going to be a little generous to me and allow me around $300 (30,000 Japanese yen) to spend as I please. I have decided to spend it on computer components of some kind. My first two choices are either a new cpu or a new video card (thinking HD 6870). I use my PC mainly for gaming, watching movies, and other general things.
My rig is as follows:

Gigabyte DS3L-P45
4x1 gb OCZ DDR2 800mhz ram
Intel e6750 (mildly overclocked to 2.8ghz)
ATI HD 4870 512mb
600w OCZ powersupply
3.1 TB of storage (4 HDDs)
LG Blu-Ray Drive
40 inch Sharp 1080p TV as monitor

So, I have a good idea of what video card I would get, HD 6870, but if I'm to get a CPU I would have to choose between the Q8400 and the Q9400, and maybe it is possible to find the Q9505 here, although I would have to get that one online probably. So, which is the better investment for gaming?

A third option is to look for a media player and a portable HDD if needed.

Forgot to mention, I like playing FPS games the most, although I do play some platformers and strategy games from time to time.

Thanks in advance.

  1. Well E6750 is a core 2 duo, its fine, unless you want a quad core. My guess, get a new gpu, you have 600 W, it will be enough to handle most new cards- Hd 6870
  2. Unless your games demand quad core power :

    Conclusion: A Trend Toward 3+ Cores

    The average optimal number of CPU cores suggested by the test results is 2.75, showing a clear trend towards at least three CPU cores.The question of whether the CPU or GPU is most important is easily answered. If you don't have a multi-core CPU, then upgrade it. If you have a dual-core CPU at around 3 GHz, then invest your money into a graphics card, as most games are GPU-limited. This is not something that will change with new DirectX 11 games.
  3. Ok, so I went to the store tonight to buy an HD 6870, but plans changed a little. Most of the shops were closed, but at the one that was still open the cheapest 6870 was 24,980 yen (so lets say around $260). I was willing to pay this, but then I seen that all the 5850s they had in stock were priced at 18,900 yen (around $200). After lots of indecision (with the last sales people waiting for me to decide so they could go home), I went with a PowerColor 5850 (AX5850 1GBDH5), which has an after market cooler.

    What do you guys think? Saving $60 make up for the performance and features difference?
  4. Definitely the 6870 is faster-
    Well, 5850 is a good card-
  5. the 5850 will be fine.
  6. Yeah, I think it will work good. I can tell it's faster than my 4870 512.
    It also runs really cool. Idle it's sitting at 33 degrees right now (probably around 20 or under in my apartment), and running it stays under 60. Also, quieter.

    Just wish I could get crysis warhead to not open in 24hz in full screen.
