I run those games with a 2.53ghz dual core and dont really notice any lag or drop below 30fps. i doubt that the extra .53ghz i have would be that much of a difference. I also run a hd 7770 on mine tommyb13662

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

My cousin's 8600GT graphics card is almost dead after using nearly 5 years and want to buy new graphics card with no power connectors because his power supply dont have power connectors. So i told him to buy HD 7750.

Now my question is how much bottleneck will occur btw. HD 7750 and Core 2 Duo E4400 for 1280x720 Res. ? Even after Bottleneck can he get Average of 30FPS in medium or high settings for games like Battlefield 3, Grid 2, Black ops 2 and upcoming games.

Bottleneck will only reduce FPS or it will occur micro stuttering or something ?

He will buy entire new sytem with powerful graphics card later after 1 year....But for now he can only buy HD 7750...Also tell me which is best brand for HD7750...ASUS or Sapphire...

7750 can have clock speed of 900Mhz i.e. 100 Mhz higher than stock. Make sure you buy with GDDR5 type memory.

Change mobo to Asrock z77 extreme 6, will you use this PC for anything other than games? if no, get the 3570k or 2500k.

What PSU's can you choose from?

2 4GB's are better.

I use my PC for everything movies,musics,applications,internet...

Tell me some good PSU's, ur Corsair TX 650 will it support AMD crossfire of cards like HD6850 or HD 7850 ? coz. in corsair site it shows it support NVidia SLI nothing about AMD http://www.corsair.com/tx650w.html/

Yes my PSU can easily do crossfire 6870's, mine is running 2 very power hungry cards, the 8800GTS (512) and the GTX470. 2 6870's is easy, The motherboard is good but its a little outdated now, its a p67 chipset. Are there any z77 chipsets in the shop? it will say in the name.

Don't listen to anyone, I have that exact same build right now. And i had both GPU cars and I am currently using the 6870 right now. I love it and it feels a lot better!
