Upgrading computer for a good 1080p resolution

Hi,

System:
E6400 @ 2.1 GHz => changed cooler (waiting for the thermal paste to put it and O/C)
Kingston 300MHz => PI black g.skill 800MHz 4-4-4-12 (waiting to receive it)
P5B dlx
PSU anthec - i think it is 550W

Are you trying to watch blu-rays or gaming. If you're just watching blu-rays then really most any graphics card will do. Try something like a 4650. If you're gaming, then consider getting one of the new ATI 5000 series. They're supposed to be much better than current models, especially at the lower end.

@carpenter

The E6400 is overclockable to 3.2GHz. It really depends what kind of game you play. Some require more than 2 cores, faster FSB or frequency. In the case of the E6400, it has only 2 cores thus I won't invest more than 250$ for a G/C because it's just going to be a waste.

@jaguarskx Well, I'll wait one more day I think xD.

Anyway care to get some GPU with minimum 1Gb Video RAM. It'll help in that resolution..

@sid Gaming - that's why I upgrade it.

BTW, I'd like to see a link carpenter b/c your source(s) seem(s) to not be really fiable.
Why do I say that?
I don't know if you take in consideration that some game are more CPU demanding than some. Same thing for the G/C. I think it really depends what kind of game you play, what is your resolution, etc. It's sure that a good system in 1920x1080 may sucks at 2560x1600, but you simply can't generalise for every situation.
I may be wrong, but I think that 3.2GHz is suffisant for actual bottom line G/Cs.

i use the 5870 on my amd 6000+ for 1080p gaming....and am fully satisfied, all settings on at high..maxed af and sometimes maxed aa gets me 40~70 fps

I can't give you any links, because I am speaking of my own experience. I have an E6400 and a 4850 and it is NEVER used at its full speed. I think only Crysis has taken it to 100%. When I benchmark with gpu-z, which shows you what percentage of your card is used, it is around 50-80% all the time, while the cpu usage approaches 100% (for one core or two cores, depending on the game; I still play some games that have minimal or no multicore support like TF2 and NW2).

I told you that I have oc'ed my E6400 to 2.56. I do believe however that if you manage to OC it to 3.2, then a 4850 or a 4870 should not be a bottleneck, especially at your resolution.

I play at 1440x900 and with some games I get low fps. Crysis with a mix of mid-high settings, I get 25-40 fps (lower in a really heavy battle). In TF2 depending on the situation I get from 35 to 140. I used to get 20 before overclocking.

Anyway, I am not saying you should buy a 4850 and nothing better (I am not that pleased with my card; ever since I got it it idles at around 70 degrees). DX11 comes out, so it would be wise to go with a 5xxx, especially if you plan on getting Windows 7. I am just saying that with your cpu (and mine, remember that), there is no way that the graphics card is going to be used at its full capacity. That's why I suggested the 5770. If it's any good, it sounds ideal for your system.

In any case, I hope you enjoy your purchase.
