Would a 2.8Ghz PentiumD BOTTLENECK a 4890?

I'm looking into buying an Asus HD4890 (for the voltage tweak) BUT, this is a big but, would my 2.8Ghz dual core CPU bottleneck it?
Also, could bottlenecking be avoiding by overclocking my processor?

Thanks,
Fledge.
 
If it's a Pentium D, then yes it would almost certainly. I'd advise upgrading to at least a Pentium Dual Core E2000/5000 series processor, or an Athlon X3 or Core 2 Duo if you're looking at a card of that sort of calibre.
 
YES! Bottleneck and a half! Im assuming its not the Core 2 bases pentiums?

Either way, unless your doing 30" resolutions and max AA and AF it will be a huge one :/
 
Definitely bottled. Hell I saw a 33% gain in framerates going from a 4200x2 at 3ghz to a q6600 at 3.6ghz with a GTS 8800 512 (heavily overclocked)
 
What do you use your system for? You might be better off buying a second hand E8400~ and a 4850/4870. Thats if your motherboard will support the E8xxx series or earlier?
 
yes it would bottlenect quite badly particauly for games that are nasty on the cpu (sup com)

I am with above you might as well get a decent core 2 duo, but than again your mobo can it take it...should do if LGA755 might have to do BIOS UPDATE through
 
Agree it will, but if you want to buy it, just buy it! you should be able to play any game with it ;)

I have an opteron at 2820 mhz which is also old tech but still getting good performance with any current game and even reaching P12387 (GPU 10443 but CPU only 27008 thanks to physx enabled) with 3DMark Vantage.

I had this exact CPU and went from a 7900GS to a 9800GT. The new graphics card barely made a difference. It wasn't until I upgraded to a Core 2 Duo that I saw the benefit
 
all depends on the game really. there is always a bottleneck somewhere though. the games you currently play will all look better and play better regardles but a 4870 1gb would probably act exactly the same as a 4890 in your case. even all that overclocking would be pretty useless... (but fun :) )

I had a similar situation wherein I had a 1.6GHz stock E2140, I'd just upgraded from a X1650 Pro to an 8800 GTS 320MB. Whilst there was definitely a difference it was a little underwhelming, games were still jumpy and such. I got a far larger boost in performance from overclocking the CPU to 3GHz.

Going from 3.0 --> 3.6 (now 3.8) GHz on an E8400 made a huge difference on my 4870 1GB. If a stock 8400 is a bottleneck, the pentium D will be too.

Depends on res. Cpu is less of a bottleneck at higher resolutions.

But yes, as stated it will be a bottleneck but lets say his current card gives him 40 fps and the new one with a 3.6 dual/quad should give 100 fps but the cpu bottleneck drops it by 30-40%, he would still see a doubling in performance.

This is just a wild example.

It's a bit out of date but this gives you the idea

What are the rest of your specs though? Ram, mobo, heatsink/fan andPSU (might not be able to handle the power of 4890) and what resolution do you game at?

If you have 2gb or more memory, your psu is a good make 450-500w+, you have a good overclockable mobo and decent cooling I would get the 4890 and clock the nuts off your Pentium D. I remember you could get them to the 4ghz mark easily enough. At this speed it should be fine and upgrade to Core 2 in due course ;)
 
Pentium D... used to have this CPU!
finished Crysis on it with old X1950pro ...

I wouldn't recommend to overcklock it, but get card, u'll c huge improvement!
and when you have money get new CPU and mobo...

I feel like my E8500 on stock 3.16ghz bottlenecks my GTX280 according to 3Dmark06 and Vantage..!
