pentium D bottleneck 3850 or 3870?

[rumbl3]

My buddy has a alienware system with a pentium D i think a 805 or something when we get out of work im gonna run cpu-z on it and find out exactly. He wants a new video card.

Just curious if a 3850 or 3870 will bottleneck really bad? should he get a new processor also? Gonna find out what mobo he has too. So we can see what options he has for upgrading.

Right now he has a 7900 GT in his machine, 1 gig of ram.

I would expect some degree of bottlenecking, or a lot... OMG what a nightmare the 800 series dualcores were. Hot and slow, a new MB and CPU should be your friends first priority, the screencard is the best part he got

If he really want a new screencard in that rig then get 8800GT, or at least 3870 if he want ATI. 7900GT to 3850 is a wasted upgrade IMO, remember 3850 cannot outperform 7900GTX in most AA enabled benches so its not that far ahead of 7900GT. Without AA its acceptable, performance at the price of jaggies...

Yes it will bottleneck those cards. Id upgrade to a Core 2 duo system. There was a deal for a Pentium Dual Core and board for 80 bucks. The Pentium Dual core is based off of the core 2 duo which in turn gives it a huge performance advantage over any netburst CPU.

when i went from a d920 to a e6600 my 3dmark 06 score went up 3.5K

well i can say the card he is prolly running now is being bottlenecked by that cpu, even if it is dual core...

i went from my P4 3.0c @3.6ghz, holding back my 6600GT. To using a [email protected] being held back by the video card...

i can speak from experience, i have a pentium d 930, and it is bottle nexkngi my card BAD, everyone else gets 10k-11k easy stock with the conroe cpus, i get 6k

edit:

also my gf has a laptop with a t5500 in it 1.66ghz, c2d, it runs superpi in 34secs, my pentioum d 930 3ghz runs it in 44secs.... so its %25 faster and a good 46% slower "clock wise".
